Description:    The motion of a massive test particle in a Schwarzschild spacetime surrounded by a perfect fluid with equation of state p 0 = wρ 0 is investigated. Deviations from geodesic motion are analyzed as a function of the parameter w , ranging from w =1, which corresponds to the case of massive free scalar fields, down into the so-called “phantom” energy, with w 〈−1. It is found that the interaction with the fluid leads to capture (escape) of the particle trajectory in the case 1+ w 〉0 (〈0), respectively. Based on this result, it is argued that inspection of the trajectories of test particles in the vicinity of a Schwarzschild black hole with matter around may offer a new means of gaining insights into the nature of cosmic matter.

Description:    A possibility of KLOE-2 experiment to measure the width and the π 0 γγ ∗ form factor F ( Q 2 ) at low invariant masses of the virtual photon in the space-like region is considered. This measurement is an important test of the strong interaction dynamics at low energies. The feasibility is estimated on the basis of a Monte-Carlo simulation. The expected accuracy for is at a per cent level, which is better than the current experimental world average and theory. The form factor will be measured for the first time at Q 2 ≤0.1 GeV 2 in the space-like region. The impact of these measurements on the accuracy of the pion-exchange contribution to the hadronic light-by-light scattering part of the anomalous magnetic moment of the muon is also discussed.

Description:    We evaluate all two-body decay modes of the gluino, in the Minimal Supersymmetric Standard Model with complex parameters (cMSSM). This constitutes an important step in the cascade decays of SUSY particles at the LHC. The evaluation is based on a full one-loop calculation of all two-body decay channels, also including hard QED and QCD radiation. The dependence of the gluino decay to a scalar quark and a quark on the relevant cMSSM parameters is analyzed numerically. We find sizable contributions to the decay widths and branching ratios. They are, roughly of , but can go up to ±10% or higher, where the pure SUSY QCD contributions alone can give an insufficient approximation to the full one-loop result. Therefore the full corrections are important for the correct interpretation of gluino decays at the LHC. The results will be implemented into the Fortran code FeynHiggs .

Description:    Deep-inelastic positron-proton scattering events at low photon virtuality, Q 2 , with a forward jet, produced at small angles with respect to the proton beam, are measured with the H1 detector at HERA. A subsample of events with an additional jet in the central region is also studied. For both samples, differential cross sections and normalised distributions are measured as a function of the azimuthal angle difference, Δ ϕ , between the forward jet and the scattered positron in bins of the rapidity distance, Y , between them. The data are compared to predictions of Monte Carlo generators based on different evolution approaches as well as to next-to-leading order calculations in order to test the sensitivity to QCD evolution mechanisms.

Description:    We analyze the effect of higher derivative corrections to the near horizon geometry of the extremal vanishing horizon (EVH) black hole solutions in four dimensions. We restrict ourselves to a Gauss–Bonnet correction with a dilation dependent coupling in an Einstein–Maxwell-dilaton theory. This action may represent the effective action as it arises in tree level heterotic string theory compactified to four dimensions or the K3 compactification of type II string theory. We show that EVH black holes, in this theory, develop an AdS 3 throat in their near horizon geometry.

Description:    We show how the measurement of appropriately constructed particle-energy/momentum correlations allows access to the bulk viscosity of strongly interacting hadron matter in heavy-ion collisions. This measurement can be performed by the LHC and RHIC experiments in events with high-particle multiplicity, following up on existing estimates of the shear viscosity based on elliptic flow.

Description:    Modified gravity scenarios where a change of regime appears at acceleration scales a 〈 a 0 have been proposed. Since for 1 M ⊙ systems the acceleration drops below a 0 at scales of around 7000 AU, a statistical survey of wide binaries with relative velocities and separations reaching 10 4 AU and beyond should prove useful to the above debate. We apply the proposed test to the best currently available data. Results show a constant upper limit to the relative velocities in wide binaries which is independent of separation for over three orders of magnitude, in analogy with galactic flat rotation curves in the same a 〈 a 0 acceleration regime. Our results are suggestive of a breakdown of Kepler’s third law beyond a ≈ a 0 scales, in accordance with generic predictions of modified gravity theories designed not to require any dark matter at galactic scales and beyond.

Description:    We provide a systematic study of charmless B s → PP , PV , VV decays ( P and V denote pseudoscalar and vector mesons, respectively) based on an approximate six-quark operator effective Hamiltonian from QCD. The calculation of the relevant hard-scattering kernels is carried out, the resulting transition form factors are consistent with the results of QCD sum-rule calculations. By taking into account important classes of power corrections involving “chirally enhanced” terms and the vertex corrections as well as weak annihilation contributions with non-trivial strong phase, we present predictions for the branching ratios and CP asymmetries of B s decays into PP, PV and VV final states, and also for the corresponding polarization observables in VV final states. It is found that the weak annihilation contributions with non-trivial strong phase have remarkable effects on the observables in the color-suppressed and penguin-dominated decay modes. In addition, we discuss the SU(3) flavor symmetry and show that the symmetry relations are generally respected.

Description:    It has been shown that the description of the details of the electronic spectra obtained by the combination of the dynamical mean field theory, quantum Monte Carlo methods, and the maximum entropy method can be significantly improved by changing the last method to optimal regularization of the analytic continuation of the Green’s function to the real frequency axis. Starting with the quantum Monte Carlo data, this method has reconstructed peaks in the structure of Hubbard subbands with a maximum error of 0.001 to 0.01. Owing to the universality of the quantum Monte Carlo method, by varying hybridization, it is possible to determine the features of the hybridized function that are responsible for the formation of the structure of Hubbard subbands. It has been shown that there is no direct relation between the peak structure of subbands and the central Kondo peak. The result indicates the charge nature of resonances responsible for the formation of the peak structure.

Description:    The spallation of a nanometer-thick melt layer on a GaAs surface during its ablation by femtosecond laser pulses occurs with subnanosecond delays and lift-off velocities that depend on the laser fluence after its complete thermal (hydrodynamic) expansion/acoustic relaxation. The position of the spall interface in the melt is determined by the depth of the formation of a two-dimensional subsurface layer of nanobubbles (nanofoam), whereas the strongly heated surface layer of the melt above the nanofoam is partially removed in the form of a vapor-drop mixture. At the thermal expansion stage, acoustic reverberations are observed in the melt layer and characterize both the dynamics of an increase in its thickness and the shift of the cavitation region (nanofoam) inside the melt. Moreover, these reverberations can additionally stimulate spallation, promoting cavitation in the completely unloaded melt in the case of passage of a weak rarefaction wave.

Description:    The current 7 TeV run of the LHC experiment shall be able to probe gluino and squark masses up to values larger than 1 TeV. Assuming that hints for SUSY are found in the jets plus missing energy channel by the end of a 5 fb −1 run, we explore the flavour constraints on three models with a CMSSM-like spectrum: the CMSSM itself, a seesaw extension of the CMSSM, and Flavoured CMSSM. In particular, we focus on decays that might have been measured by the time the run is concluded, such as B s → μμ and μ → eγ . We also analyse constraints imposed by neutral meson bounds and electric dipole moments. The interplay between collider and flavour experiments is explored through the use of three benchmark scenarios, finding the flavour feedback useful in order to determine the model parameters and to test the consistency of the different models.

Description:    In this work, we have considered the power-law correction of entropy on the horizon. If the flat FRW Universe is filled with the n components fluid with interactions, the GSL of thermodynamics for apparent and event horizons have been investigated for equilibrium and non-equilibrium cases. If we consider a small perturbation around the de Sitter spacetime, the general conditions of the validity of GSL have been found. Also if a phantom dominated Universe has a pole-like type scale factor, the validity of GSL has also been analyzed. Further we have obtained constraints on the power-law parameter α in the phantom and quintessence dominated regimes. Finally we obtain conditions under which GSL breaks down in a cosmological background.

Description:    This paper reports on a study of the Seebeck coefficient and power factor κ of p -Bi 2 − x Sb x Te 3 solid solutions with different contents of antimony atoms in the bismuth sublattice for x = 0, 1.4, 1.5, and 1.6 under variation of pressure of up to 15 GPa. The magnitude of κ has been found to grow nonmonotonically within the pressure region of 2–4 GPa. The effective mass of the density of states m / m 0 and the mobility μ 0 have been calculated with due account of degeneracy within the parabolic model of the energy spectrum assuming isotropic charge carrier scattering. It has been shown that application of pressure brings about a decrease of the effective mass m / m 0 and an increase of carrier mobility. The power factor κ of the p -Bi 0.6 Sb 1.4 Te 3 composition exhibits at the pressure P ≈ 4 GPa the largest increase of the power factor κ as a result of a weak decrease of the effective mass m / m 0 and an increase of carrier mobility as compared to the other solid solution compositions. The specific feature of the variation of the power factor κ with a change of the pressure in bismuth telluride near P ≈ 3 GPa, which is accompanied by formation of a knee in the m / m 0 vs. P dependence, can be assigned to an electronic topological transition.

Description:    Neutron diffraction studies of many magnetoelectrics and corresponding symmetry analysis indicate that the description of their magnetic structures requires of invoking two or more order parameters, so that the temperature proximity of their “condensation” has to be postulated when constructing a consistent thermodynamic theory. In this work, MnWO 4 , CuO, and CuCl 2 magnetoelectrics are analyzed from the standpoint of symmetry of the exchange Hamiltonian. The magnetically ordering states observed in them are shown to be induced by one irreducible representation of the symmetry group of the exchange Hamiltonian. This fact provides the proximity of corresponding instabilities in the thermodynamic path and some features of magnetoelectrics.

Description:    Dispersion properties of circularly polarized eigenwaves propagating in the “semiconductor-magnet” layered periodic structure along the axis of its periodicity and external magnetic field have been considered. The possibility of controlling the effective material parameters of the structure and the feasibility of negative refractive index for the wave with right (resonant) circular polarization has been shown. High magneto-optical activity of this gyrotropic structure has been ascertained, which leads to large Faraday rotation angles if the structure is in the state of “left-handed” medium.

Description:    The interaction of ytterbium nanofilms evaporated on tungsten substrates with oxygen has been studied by Auger electron spectroscopy, thermal desorption spectroscopy, and contact potential difference measurements. It has been shown that at room temperature, no oxide is formed in the above interaction. In place of the oxide, a chemisorbed layer of nondissociated O 2 molecules is formed on the surface of the ytterbium nanofilms. This layer modifies the ytterbium. This modification transforms ytterbium from the divalent state into the trivalent state.

Description:    The behavior of the impedance spectra of island permalloy films prepared through vacuum evaporation onto optically polished glass-ceramic substrates has been investigated in the frequency range from 0.0001 to 100 MHz. A resistor-capacitor model of the films has been developed and the model parameters, for which there is a good agreement with experimental data on the frequency dependences of the real and imaginary components of the impedance, have been determined. The specific features in the behavior of the electrical and physical characteristics with variations in the thickness of the sample and the gap between the measuring electrodes have been investigated. It has been found that the relative permittivity of the films under investigation reaches values ɛ ∼ 10 7 –10 8 . The structural relaxation times have been calculated.

Description:    The influence of the first-order phase transition on the parameters of the potential barrier at the indium/polymer interface has been investigated. It has been established that the phase transition occurring in the metal initiates switching of the polymer insulator into a high-conductivity state. Performed investigations have shown that the main charge transfer mechanism in the metal-polymer-metal structure at high temperatures is the current caused by the electron thermionic emission. The analysis of current-voltage characteristics has demonstrated that the first-order phase transition in indium leads to the variation in the potential barrier height at the metal/polymer interface by Δφ ≈ 0.18 eV. It is this phenomenon that is responsible for the electronic switching. Content Type Journal Article Category Metals Pages 243-247 DOI 10.1134/S1063783412020199 Authors I. R.

Description:    A model of electron transfer by tunneling between trapped electron and hole centers in crystals with hydrogen bonds under the conditions of thermostimulated mobility of one carrier type in the recombination process has been developed. The proposed model describes all features in the kinetics of induced optical density relaxation observed in nonlinear optical crystals of KH 2 PO 4 (KDP) and NH 4 H 2 PO 4 (ADP) on a wide temporal scale (10 −8 –10 s) under pulsed irradiation. The results of model calculations have been compared with experimental data on the photoinduced transient optical absorption (TOA) in KDP and ADP crystals in the visible and UV ranges. The nature of the radiation-induced defects, which account for the TOA, and the dependence of the TOA decay kinetics on the temperature, excitation power, and other experimental conditions have been considered.

Description:    The differential magnetization of LaCoO 3 in magnetic fields of up to 500 T has been measured at a temperature of 4.2 K. The magnetization curve reveals several features which suggest a complex pattern of the transition of LaCoO 3 from the low-spin state to the high-spin state. The magnetic moment starts to grow in fields above 50 T to reach a plateau in the 130–240-T region, after which the magnetic moment continues to rise up to saturation in fields ∼500 T.

Description:    The magnetic-field-induced optical alignment-orientation transition in a system of triplet bound excitons in a resonantly excited GaSe crystal has been studied using optical spectroscopy. It has been demonstrated that this effect can be assigned to a variation of the properties of Zeeman (spin) states of triplet excitons in a magnetic field, which initiates a change in the optical activity of these states in circularly and linearly polarized light. For the transition to become possible, the model requires that the electronic system of the crystal supports spin-orbit coupling. The approach employed permits the adequate description of experimental data, as well as calculation of the evolution of the effect during the bound-exciton lifetime.

Description:    We establish an extended version of the Einstein–Maxwell-axion model by introducing into the Lagrangian cross-terms, which contain the gradient four-vector of the pseudoscalar (axion) field in convolution with the Maxwell tensor. The gradient model of the axion–photon coupling is applied to cosmology: we analyze the Bianchi-I type Universe with an initial magnetic field, electric field induced by the axion–photon interaction, cosmological constant and dark matter, which is described in terms of the pseudoscalar (axion) field. Analytical, qualitative and numerical results are presented in detail for two distinguished epochs: first, for the early Universe with magnetic field domination; second, for the stage of late-time accelerated expansion.

Description:    Grand Unified Theories often involve additional Abelian group factors, apart from the standard model hypercharge, that generally lead to loop-induced mixing gauge-kinetic terms. In this letter, we show that at the one-loop level this effect can be avoided in many cases by a suitable choice of basis in group space and present a general scheme for the construction of this basis. In supersymmetric theories, however, a residual mixing in the soft SUSY breaking gaugino mass terms may appear. We generalize the renormalization group equations for the gaugino mass terms to account for this effect. In a further calculation we also present the necessary adjustments in the renormalization group equations of the trilinear soft-breaking couplings and the soft-breaking scalar mass squares.

Description:    The conformal invariance of the Hawking temperature, conjectured for the asymptotically flat and stationary black holes by Jacobson and Kang, is semiclassically evaluated for a simple particular case of symmetrical spherically and non-asymptotically flat black hole. By using the Bogoliubov coefficients, the metric euclideanization, the reflection coefficient and the gravitational anomaly, as methods of calculating the Hawking temperature, we find that it is invariant under a specific conformal transformation of the metric. We briefly discuss the results for each method.

Description:    A planar homogeneous waveguide array with two-level systems has been considered. The evolution of an electromagnetic field is described by the Maxwell-Bloch equations taking into account the action of the fields of neighboring waveguides beyond the slow-envelope approximation. It has been shown that the model in the continuous approximation is reduced to an integrable system of equations, including the case of a nonzero static dipole moment. The model can be used to analyze the nonlinear mechanism of the compression of pulses and the conditions of overcoming of the diffraction limit.

Description:    An array of non-overgrown InAs/GaAs quantum dots has been decorated with adsorbed metal atoms in situ in ultrahigh vacuum. Their electron and photoemission properties have been studied. The radical modification of the spectra of the threshold emission from the quantum dots with increasing cesium coating has been found. Two photoemission channels have been established; they are characterized by considerably different intensities, spectral locations, and widths of the selective bands. It has been shown that the decoration of the quantum dots makes it possible to control the electronic structure and quantum yield of photoemission, the nature of which is related to the excitation of the electronic states of the GaAs substrate and InAs/GaAs quantum dots.

Description:    In this paper, we consider a theory of gravity with a metric-dependent torsion namely the F ( R , T ) gravity, where R is the curvature scalar and T is the torsion scalar. We study the geometric root of such theory. In particular we give the derivation of the model from the geometrical point of view. Then we present the more general form of F ( R , T ) gravity with two arbitrary functions and give some of its particular cases. In particular, the usual F ( R ) and F ( T ) gravity theories are particular cases of the F ( R , T ) gravity. In the cosmological context, we find that our new gravitational theory can describe the accelerated expansion of the Universe.

Description:    This paper reports on the results of the investigation into the dielectric properties of perovskite ceramics of the relaxor ferroelectrics (1 − x )(NaBi) 1/2 TiO 3− x Bi(ZnTi) 1/2 O 3 ( x 〈 0.2) with the use of the impedance spectra measured in the frequency range from 25 to 106 Hz at temperatures from 100 to 1000 K. It has been found that the temperature dependence of the real part of the permittivity is characterized by a maximum at a temperature T ′ m (590–610 K). It has been shown that, in the temperature region of the existence of the relaxor state ( T 〈 T ′ m ), the permittivity ɛ is determined by the sum of the contributions from the matrix and dipole clusters. The temperature dependence of the contribution from the clusters, which is determined by the kinetics of their formation and freezing, is characterized by a curve with a maximum. It has been revealed that, in the temperature range T 〉 T ′ m , there are two mechanisms of polarization. One mechanism is associated with the thermal hopping motion of charges, whereas the other mechanism provides an induction-type response (system with a negative capacitance). The latter makes a negative contribution to the real part of the permittivity ɛ and a positive contribution to the imaginary part of the permittivity. A quantitative analysis of the experimental data has been carried out with the use of an equivalent circuit that includes a constant-phase element of the induction type.

Description:    A model has been developed for nucleation and growth of particles of the second phase in alloys based on the Fe-Cr system. It has been assumed that the main mechanisms of change in the distribution of phases in the alloy are the fluctuation activationless nucleation of clusters enriched with chromium and their subsequent growth due to the diffusion of chromium atoms. The model is applied to the description of the growth kinetics of particles of the second phase in the alloy Fe- x Cr ( x = 14, 16, 18, 20 at %) at the temperature T = 500°C. The obtained values of the diffusion coefficient D Cr = 3.12 × 10 −19 cm 2 /s and the rate of fluctuation nucleation (decomposition) of the clusters τ −1 = 0.868 × 10 −3 s −1 are consistent with the data available in the literature.

Description:    Based on the developed technique for synthesizing spherical mesoporous particles of yttrium oxide with a size dispersion of 10–15% and methods for infiltrating active components into them, spherical nanocrystalline particles of composition Y 2 O 3 -ZnO have been synthesized. The nanocomposite structure has been studied, and the spectra of diffuse reflection and photoluminescence of heteroparticles, as well as the stimulated emission spectra of zinc oxide excitons, have been analyzed after annealing at various temperatures. The formation of ZnO nanocrystals in Y 2 O 3 sphere pores is observed during material synthesis with a single infiltration procedure. The lasing is associated with a change in the effective refractive index and local photon density of states in phosphor nanoparticles, i.e., spherical optical cavities.

Description:    The characteristics of the microhardness and microplasticity of ionic single crystals related to the dislocation structure formed in the near-surface layer of the samples around the indentor print have been analyzed. It has been shown that the most informative characteristic of the contact microplasticity reflecting both the bulk and surface properties of materials is the so-called “ray ratio,” i.e., the ratio of the lengths of edge l e and screw l s “arms” of dislocation indentation rosettes θ = l e / l s .

Description:    The spectral and temporal characteristics of X-ray luminescence of composites consisting of microparticles of “heavy” components (oxides, fluorides, sulfates) and an organic polymer binder containing optically active impurities have been investigated. It has been found that, in the case of pulsed X-ray excitation of the composites with a photon energy of 130–150 keV, the fast component (τ 〈 10 ns) of the luminescence arises whether or not the “heavy” component of the composite is doped with an optically active impurity. A mechanism has been proposed for the formation of the fast component of the luminescence: electrons and low-energy X-ray photons generated during the interaction of high-energy X-ray photons with the “heavy” component of the composite are effectively absorbed by the polymer binder and, thus, induce its luminescence. It has been shown that, in order to produce a composite-based fast scintillator with a high light yield, it is necessary to use a binder prepared from an organic material with a short scintillation decay time and another component prepared from a compound whose composition includes an element of a large atomic number Z .

Description:    The X-ray diffraction investigations have been performed for nanocomposite materials based on porous aluminum oxide with inclusions of TGS and TGS, which is doped with L ,α-alanine (ATGS). The presence of the TGS and ATGS textures in pores of Al 2 O 3 films has been found. It has been established that, under conditions of confined geometry, the broadening of diffraction maxima of the reflection is caused by the size effect. The temperature dependences of the order parameter for porous aluminum oxide with TGS inclusions have been constructed.

Description:    The phenomenon of surface plasmon resonance in composite films consisting of gold nanoclusters in matrices of organic molecular materials calix[4]arene and poly(N-vinylcarbazole) has been investigated. The internal reflection coefficients R s 2 and R p 2 of s - and p -polarized light and their physical difference ρ = R s 2 − R p 2 have been measured according to the Kretschmann scheme as a function of the angle of light incidence θ at different wavelengths λ in the range 400–1000 nm. The angular characteristics reflect the cluster structure of the films, which is confirmed by electron microscopy. A topological size effect has been revealed. This effect is associated with the dependence of the excitation energy efficiency of surface plasmons on the azimuth of the linearly polarized light, the shape, and the distribution of nanoclusters in the coordinate space. The dependences ρ(λ) demonstrate that the local plasmon resonance is excited by both s - and p -polarized light, whereas the polariton resonance is excited by s -polarized light. The sign of the curvature of the dependence ρ(θ) determines the predominance of the excitation energy efficiency of electromagnetic modes with one of the two states of polarization of the excitation radiation.

Description:    The domain structure in a biaxial ferroelectric layer perforated by cylindrical channels has been investigated using the numerical simulation based on the phenomenological theory of ferroelectricity and the equations of electrostatics in the framework of the Gauss-Seidel iterative method. Both polar axes lie in the plane of the film, which is characteristic of thin epitaxial films of BaTiO 3 and (Ba 1 − x Sr x )TiO 3 on a MgO substrate. The calculations have been performed using the parameters of BaTiO 3 , which does not matter because of the qualitative character of the results: the electrostatic problem is two-dimensional and formally applies to infinitely thick layers rather than to thin layers. The primary attention has been paid to the systems containing sixteen channels. Two different orientations of the polar axes with respect to the lattice channels have been considered. It has been shown that, for these orientations, the domain structure has a different character: when the line with the minimum distance between the channels is perpendicular to the bisector of the angle between the polar axes, this structure contains a single channel in the repeating motif and a polarization vortex; when one of the polar axes is perpendicular to the line with the minimum distance between the channels, the situation is less clear. There are indications that the repeating motif of the domain structure in a system of many channels contains two channels and does not contain vortices. The strong influence of the electrodes on the domain structure in this case has been noted.

Description:    The 55 Mn NMR studies of nano-sized and polycrystalline La 1 − x Ca x MnO 3 samples have been performed. It has been shown that a decrease in the average size of the nanoparticles leads to the disappearance of the phase separation of the ferromagnetic phase, which is likely a general property of manganites. The studies in constant magnetic fields have demonstrated that the phase separation under consideration occurs within domains rather than as a result of the separation of the samples into domains and domains walls.

Description:    The s -wave kaon–antikaon ( ) scattering length is studied by lattice QCD using pion masses m π =330–466 MeV. Through wall sources without gauge fixing, we calculate four-point functions in the I =1 channel with the “Asqtad”-improved staggered fermion formulation, and observe an attractive signal, which is consistent with pioneering lattice studies on potential. Extrapolating the scattering length to the physical point, we obtain , where the first error is statistical and the second is systematic. These simulations are conducted with MILC gauge configurations at lattice spacing a ≈0.15 fm.

Description:    Recently, Kostelecky [V.A. Kostelecky, Phys. Lett. B 701 , 137 ( 2011 )] proposed that the spontaneous Lorentz invariance violation (sLIV) is related to Finsler geometry. Finsler spacetime is intrinsically anisotropic and naturally induces Lorentz invariance violation (LIV). In this paper, the electromagnetic field is investigated in locally Minkowski spacetime. The Lagrangian is presented explicitly for the electromagnetic field. It is compatible with the one in the standard model extension (SME). We show the Lorentz-violating Maxwell equations as well as the electromagnetic wave equation. The formal plane wave solution is obtained for the electromagnetic wave. The speed of light may depend on the direction of light and the lightcone may be enlarged or narrowed. The LIV effects could be viewed as influence from an anisotropic media on the electromagnetic wave. In addition, birefringence of light will not emerge at the leading order in this model. A constraint on the spacetime anisotropy is obtained from observations on gamma-ray bursts (GRBs).

Description:    The mass spectrometry study has indicated that the magnetic field accelerates the oxidation of the surface of silicon crystals. The oxidation rate also depends on the nuclear spin of silicon: the oxidation rate of atoms with magnetic nuclei ( 29 Si) is almost twice as high as that of atoms with spinless, unmagnetized nuclei ( 28 Si and 30 Si). Both effects—magnetic field and magnetic isotope—reliably prove that the oxidation of silicon is a spin-selective reaction involving radicals and radical pairs as intermediate paramagnetic particles. A spin-selective magnetic sensitive oxidation mechanism is discussed. Content Type Journal Article Category Condensed Matter Pages 102-104 DOI 10.1134/S002136401214007X Authors O. V.

Description:    A light emitting diode has been developed on the basis of multilayer nanostructures in which CdSe/CdS semiconductor colloidal quantum dots serve as emitters. Their absorption, photo-, and electroluminescence spectra have been obtained. The strong influence of the size effect and the density of particles in the layer on the spectral and electrophysical characteristics of the diode has been demonstrated. It has been shown that the rates of the transfer of the exciton excitation energy from organic molecules to quantum dots increase strongly even at a small increase in the radius of the core (CdSe) of a particle and depend strongly on the thickness of the shell (CdS) of the particle. The optimal arrangement of the layer of quantum dots with respect to the p-n junction has been estimated from the experimental data. The results demonstrate that the spectral characteristics and rates of the electron processes in light-emitting devices based on quantum dots incorporated into an organic matrix can be efficiently controlled.

Description:    We investigate the disturbance of the InAs nanowire resistance by a conductive tip of a scanning probe micro-scope at helium temperature as a function of the tip position in close vicinity to the nanowire. At the tip displacement along the wire the resistance ( R wire ∼ 30 kΩ, what is typical for diffusive regime) demonstrates quasi-periodical oscillations with an amplitude about 3%. The period of the oscillations depends on the number of electrons in the nanowire and is consistent with expected for standing electron waves caused by ballistic electrons in the top subband of the InAs nanowire.

Description:    Schramm-Loewner evolution (SLE) and conformal field theory (CFT) are popular and widely used instruments to study critical behavior of two-dimensional models, but they use different objects. While SLE has natural connection with lattice models and is suitable for strict proofs, it lacks computational and predictive power of conformal field theory. To provide a way for the concurrent use of SLE and CFT, CFT correlation functions, which are martingales with respect to SLE, are considered. A relation between parameters of Schramm-Loewner evolution on coset space and algebraic data of coset conformal field theory is revealed. The consistency of this approach with the behavior of parafermionic and minimal models is tested. Coset models are connected with off-critical massive field theories and implications of SLE are discussed.

Description:    Spectral properties of LiFeAs superconductor are investigated within the LDA+DMFT method. Calculated distribution of the spectral weight in the k -space is in good agreement with angle-resolved photoemission (ARPES) spectra. Calculated effective electron mass enhancement factor m */ m ≈ 3 is close to the one estimated from comparison of density-functional theory results with ARPES spectra. Our results demonstrate that inclusion into consideration of dynamical Coulomb correlations between the electrons plays a key role in understanding of the spectral properties of LiFeAs.

Description:    We predict the insulator-metal-insulator transitions for the temperature and pressure of the lower mantle with the metal layer thickness Δ h ≈ 400 km at the depth of 1400–1800 km. The insulator-metal transition has the Mott-Hubbard origin, while the second transition from metal to insulator results from spin crossover of the Fe 2+ ions from high spin S = 2 to low spin S = 0 state. The conductivity in the metal layer may attain 250 S/m. The depth profile of the conductivity is also suggested.

Description:    Photoemission induced by vacuum ultraviolet resonance radiation of xenon atoms from the surface of a solid in vacuum and in the case of a target in contact with a gas has been experimentally studied. It has been demonstrated that the photoemission response increases strongly (up to an order of magnitude) under the adsorption (or implantation) of gas atoms into the target when vacuum ultraviolet radiation resonantly acts on these atoms. This is due to different mechanisms of photoemission from the surface of the solid in vacuum and from the surface in contact with the gas. The notion of activated resonant photoemission has been introduced. Content Type Journal Article Category Miscellaneous Pages 133-137 DOI 10.1134/S0021364012140032 Authors P. A.

Description:    The nature of the set of free fields that represent the system at the critical point has been revealed by studying the correlation functions of the degrees of freedom of the gauge supersymmetric Ising model on the cubic lattice. The same set of free fields represents the continuous supersymmetric Abelian gauge theory. Thus, the name of the lattice system is appropriate. Comparison with the two-dimensional Ising model is given. Content Type Journal Article Category Methods of Theoretical Physics Pages 123-128 DOI 10.1134/S0021364012140147 Authors S. N.

Description:    The influence of an electric field on stable photostimulated triplet states of NH 4 BPh 4 at a temperature of 77 K have been studied by EPR spectroscopy. It has been established that, on exposure to UV radiation, electron capture by traps in the band gaps takes place with formation of triplet state. After application of an electric field, triplet states are destructed because, with an increase in the applied voltage, a gradual inclination of energy bands takes place and electrons found in traps on different energy levels are released. The assumption that captured electrons are found in traps on different energy levels is confirmed by earlier studies of thermoluminescence spectra.

Description:    Quantum oscillations of the resistivity ρ 22 and Hall coefficient R 12.3 in the semiconductor alloy n -Bi 0.93 Sb 0.07 have been studied at H ‖ C 3 and j ‖ C 1 in magnetic fields to 14 T and at temperatures of 1.5, 4.5, 10, and 20 K. At temperatures of 1.5 and 4.5 K, beats of quantum oscillations of ρ 22 and R 12.3 due to a small deviation of the magnetic field H from the crystallographic C 3 axis have been observed. To determine the oscillation period Δ i , cyclotron mass m ci , cyclotron frequency ω ci , and extreme section S extri , experimentally measured quantum oscillation beats have been compared with the model beats of oscillations of three harmonic functions, two of which have close frequencies. The deviation of the parameters Δ i , m ci , and S extri from the same parameters when the magnetic field H exactly coincides with the trigonal C 3 axis has made it possible to estimate the magnetic field H deflection angle from the trigonal C 3 axis, which is ∼1°.

Description:    Polypropylene fibers with fillers in the form of carbon nanoparticles of four types (technical carbon, graphitized carbon nanofibers, multi-walled carbon nanotubes, and single-walled carbon nanotubes) have been synthesized. For all types of fillers, the electrical conductivity of the fibers has been measured as a function of the concentration of nanoparticles and the percolation thresholds have been determined. A correlation between the nanoparticle concentration and the electrical conductivity of the percolation cluster at the percolation threshold with the cross section, the axial ratio, and the shape of the nanoparticles dispersed in the polymer matrix has been discussed.

Description:    The results of electron paramagnetic resonance (EPR) studies of Ce 3+ impurity ions in single crystals of lead thiogallate PbGa 2 S 4 have been reported. The Ce 3+ ions substitute for Pb 2+ ions in the crystal lattice of PbGa 2 S 4 . A number of paramagnetic cerium centers in lead thiogallate have been observed. The spectra are described by the spin Hamiltonian of rhombic symmetry with the effective spin S = 1/2. The g factors of the main cerium centers have been determined. A large number of paramagnetic centers are due to both nonequivalent positions of lead and local charge compensation under the substitution Ce 3+ → Pb 2+ .

Description:    The temperature dependences of the capacitance and conductance measured for samples of porous aluminum oxide films with inclusions of triglycine sulfate have been investigated. The character of these dependences obtained for the films treated in a humid atmosphere differs from that of the corresponding dependences measured for the initial porous Al 2 O 3 matrix, bulk triglycine sulfate, and dried Al 2 O 3 + triglycine sulfate composite. The observed changes are determined by the influence of the water adsorbed on the surface of the film and the water structured in pores of the composite.

Description:    The influence of a magnetic defect on the field distribution and magneto-optical properties of a one-dimensional photonic crystal has been investigated. It has been shown that the maximum localization of the wave field in the defect layer is achieved in an asymmetric photonic crystal structure. A greater Faraday rotation, which significantly exceeds the angle of rotation of the polarization plane in an isolated magnetized layer, and a higher degree of localization of the wave field can be achieved when the magnetic layer is surrounded by layers of photonic crystal mirrors with a lower refractive index. An increase in the Faraday rotation angle is determined not only by an increase in the thickness of the magnetic defect but also by a symmetric increase in the number of periods in the photonic crystal mirrors.

Description:    This paper reports on a thermal desorption spectroscopy study of the interaction of chemisorbed molecules of oxygen and carbon monoxide with ytterbium films of nanosized thickness formed on the surface of silicon substrates at room temperature. As follows from the results obtained, at 300 K, the CO and O 2 molecules reside on the film surface in chemisorbed state and do not dissociate under these conditions into atoms. The molecules decompose at high temperatures. The oxygen released in the process reacts with ytterbium and silicon to form silicate compounds, which decompose at still higher temperatures.

Description:    The deformation surface pattern generated on the faces of a copper single crystal loaded by a compression force and simultaneously sliding over the counterbody surface has been studied. The samples under study are copper single crystals with different orientations of the compression axis, which are grown by the Bridgman method. The study of the friction of single crystals with the orientations [110] and [ - 1   11] has revealed that the shear systems whose action manifests itself on side faces are localized near the friction zones. The density of traces formed in this process decreases with the distance from the butt-end. The [110] single crystal has regions of higher density near the butt-end. Different patterns of shear on the side faces of [ - 1   11] single crystals, resulting from the friction and uniaxial compressions, have been observed: they consist in the absence of deformation macrobands during friction.

Description:    This paper reports on the results of the 57 Fe Mössbauer investigation of the short-range order in FeCoZr nanoparticles and also the studies of the electrical and magnetotransport properties of (FeCoZr) x (CaF 2 ) 100 − x granular nanocomposite films in the concentration range x = 16–75 at %. A correlation between the oxygen partial pressure during the synthesis of nanocomposites and the magnetic state of iron-containing nanoparticles has been established. The influence of the oxidation of metallic particles on the electron transport mechanisms and on the magnetoresistance of the films has been analyzed. It has been found that, in the nanocomposites with a high FeCoZr concentration ( x ∼ 70–75 at %), there is a preferred orientation of the magnetic moments of α-FeCo(Zr) nanoparticles in the direction perpendicular to the film plane.

Description:    The genetic origin of a ferroelectric crystal of guanidinium aluminum sulfate hexahydrate has been established and the spectral dependences of the electron density of states, the electron energy, and the optical functions ɛ 1 ( ħ ω) and ɛ 2 ( ħ ω) for this crystal have been calculated in terms of the density functional theory. It has been found that there is a weak dependence of the energy of electrons in the upper valence bands on the wave vector. The calculated values of the band gap ( E g ∼ 5.44 eV) and refractive indices are in agreement with the experimental results. It has been shown that there is a strong anisotropy of the spectral band ɛ 2 ( ħ ω) in the region of 6 eV, which is predominantly formed by the p states of carbon (∼60%) and nitrogen (∼40%) atoms of the C(NH 2 ) 3 group.

Description:    Samples of β-SiC/Si ecoceramics with a silicon concentration of ∼21 vol % have been prepared using a series of consecutive procedures (carbonization of sapele wood biocarbon, synthesis of high-porosity biocarbon with channel-type pores, infiltration of molten silicon into empty channels of the biocarbon, formation of β-SiC, and retention of residual silicon in channels of β-SiC). The electrical resistivity ρ and thermal conductivity κ of the β-SiC/Si ecoceramic samples have been measured in the temperature range 5–300 K. The values of ρ Si chan ( T ) and κ Si chan ( T ) have been determined for silicon Si chan located in β-SiC channels of the synthesized β-SiC/Si ecoceramics. Based on the performed analysis of the obtained results, the concentration of charge carriers (holes) in Si chan has been estimated as p ∼ 10 19 cm −3 . The factors that can be responsible for such a high value of p have been discussed. The prospects for practical application of β-SiC/Si ecoceramics have been considered.

Description:    The electronic structure of diphenylsilane Ph 2 SiH 2 has been investigated using X-ray emission spectroscopy and quantum-chemical calculations in the approximation of the density functional theory. The SiK b 1 X-ray emission spectrum of Ph 2 SiH 2 has been constructed using the results of theoretical calculations. The energy structure and shape of this spectrum are in good agreement with the experiment. A comparative analysis of the results of calculations and the fine structure of the experimental SiK b 1 X-ray emission spectrum of diphenylsilane has made it possible to describe in detail the specific features of the chemical interaction in this compound. The quantitative characteristics of the hybridization of atomic orbitals in the studied molecule have been obtained by analyzing the natural bonding orbitals.

Description:    The subnanosecond time-resolved ultraviolet luminescence of Li 6 Gd(BO 3 ) 3 : Ce crystals under selective excitation by ultrasoft X-rays in the region of the 4 d →4 f core transitions at temperatures of 7 and 293 K has been investigated for the first time. The performed investigation has revealed the following features: an intense fast component of the luminescence decay kinetics in the subnanosecond range due to the high local density of electronic excitations and the processes of Auger relaxation of the core hole; the modulation of the luminescence excitation spectrum by the “giant resonance” absorption band of the 4 d -4 f photoionization in the energy range 135–160 eV; and a new broad luminescence band at an energy of 4.44 eV due to the direct radiative recombination between the genetically related electron in the states of the conduction band bottom and hole in the 4 f ground state of the Ce 3+ ion.

Description:    A method of nondestructive control of the damaged layer and roughness parameters of the surface of a hexagonal crystal and an isotropic solid with the use of Rayleigh and shear-polarized surface acoustic waves has been proposed. The surface under study borders on vacuum and can be a rough surface or an isotropic damaged surface layer. The problem is considered in the long-wavelength limit (as compared to the roughness amplitude or the thickness of the damaged layer, as well as to the characteristic radius of the surface heterogeneity). It has been shown that, in the long-wavelength limit, the dispersion of phase velocity and the damping length of shear-polarized waves can be found from the known values of the phase velocity dispersion and the damping length of the Rayleigh surface acoustic waves or vice versa. The problem for an isotropic damaged surface layer is treated in a special case where only the density fluctuates.

Description:    Lanthanum-free high-transparency ferroelectric ceramics PbMg 1/3 Nb 2/3 O 3 − x PbZr 0.53 Ti 0.47 O 3 (PMN- x PZT) have been prepared for the first time by a two-stage sintering method. The dielectric and electro-optical properties of the PMN- x PZT ceramics of different compositions, with the values of x both far from the morphotropic phase boundary ( x = 10, 16, 23%) and close to it ( x = 33%), have been studied. It has been shown that, in compositions lying closer to the morphotropic phase boundary ( x = 23 and 33%), one observes, with no electric field applied, a first-order phase transition to a macrodomain ferroelectric phase, whereas the compositions far from the boundary ( x = 10, 16%) persist in the relaxor cubic phase down to the low-temperature domain. It has been found that, in the ceramic with x = 33%, the quadratic electro-optical coefficients have at high temperatures ( T 〉 340 K) the largest value among the relaxor systems, which expands the temperature interval of applicability of these solid solutions in industry.

Description:    Small-angle X-ray diffraction from synthetic opal films has been investigated as a function of the orientation of the sample. All the observed ( hkl ) diffraction reflections have been interpreted. The reconstruction of the reciprocal lattice of the studied opal films has been carried out. The diffraction patterns and scattering intensity profiles along chains of reciprocal lattice points have been calculated. It has been shown that, in the reconstructed reciprocal lattice of the opal films, the appearance of chains of partially overlapping nodes that are oriented along the direction Γ → L is caused by two factors: the small thickness of the film and the existence of stacking faults in it.

Description:    The effect of an external magnetic field with a strength up to 140 kOe on the phase transitions in manganese arsenide single crystals has been investigated. The existence of unstable magnetic and crystal structures at temperatures above the Curie temperature T C = 308 K has been established. The displacements of manganese and arsenic atoms during the magnetostructural phase transition and the shift in the temperature of the first-order magnetostructural phase transition in a magnetic field have been determined. It has been shown that the magnetocaloric effect in a magnetic field of 140 kOe near the Curie temperature T C is equal to Δ T ∼ 13 K. A model of the superparamagnetic state in MnAs above the temperature T C has been proposed using the data on the magnetic properties and structural transformation in the region of the first-order magnetostructural phase transition. It has been demonstrated that, at temperatures close to T C , apart from the contribution to the change in the entropy from the change in the magnetization there is a significant contribution from the transformation of the crystal lattice due to the magnetostructural phase transition.

Description:    The effect of the sintering temperature from 1070 to 1670 K of ceramic samples of lanthanum manganite La 0.7 Mn 1.3 O 3 on their grain size, structure, magnetic and resistive properties has been studied. An increase in the sintering temperature to 1270 K is shown to lead to an insignificant increase in the grain size and an increase in the density, fraction of the ferromagnetic phase in a grain, and colossal magnetoresistance. The ceramics sintering at temperatures higher than 1470 K is found to sharply increase the grain size; simultaneously, the grain takes a layered structure. The grain growth at these temperatures is established to be accompanied by manganese precipitation at the grain boundaries and likely in the grain interior. The increase in the sintering temperature is accompanied by appearance of a magnetically phase heterogeneity and a decrease in the Curie temperature and magnitude of the colossal magnetoresistance effect.

Description:    The crystal structure of two-phase and porous alkali borosilicate glasses with embedded magnetic atoms has been investigated using X-ray powder diffraction. It has been shown that, during the preparation of two-phase (nonporous) glasses, the α-Fe 2 O 3 phase undergoes a transition to magnetite (Fe 3 O 4 ) with the formation (at particular concentrations of α-Fe 2 O 3 in the initial mixture) and stabilization of the β-Fe 2 O 3 phase. The characteristic sizes of nanoparticles of iron oxides (Fe 3 O 4 and β-Fe 2 O 3 ) in these glasses have been determined. For two types of porous glasses (namely, the macroporous glass Fe20-MAP and the microporous glass Fe20-MIP), the occupancies of the octahedral (Fe 2+ ) and tetrahedral (Fe 2+ /Fe 3+ ) iron positions in magnetite have been found.

Description:    Raman spectra of ZnO and core-shell ZnTe/ZnO nanowires have been measured under conditions of nonresonant and resonant excitations by Ar + and He-Cd lasers. The optical vibration frequencies that are characteristic of the wurtzite structure of ZnO crystals have been determined. The Raman-active longitudinal optical (LO) phonons in all the studied structures have a mixed A 1 and E 1 symmetry. Surface optical modes with frequencies of 460–470 cm −1 have been found. Surface optical modes of single-layer nanowires have been analyzed using the calculation performed in the previous work by P.M. Chassaing and his colleagues, and those of double-layer nanowires have been analyzed in terms of the expressions obtained in the present work. The size of heterogeneities of the nanowires along their axis has been determined.

Description:    The quark condensate is calculated within the world-line effective-action formalism, by using for the Wilson loop an ansatz provided by the stochastic vacuum model. Starting with the relation between the quark and the gluon condensates in the heavy-quark limit, we diminish the current quark mass down to the value of the inverse vacuum correlation length, finding in this way a 64 % decrease in the absolute value of the quark condensate. In particular, we find that the conventional formula for the heavy-quark condensate cannot be applied to the c -quark, and that the corrections to this formula can reach 23 % even in the case of the b -quark. We also demonstrate that, for an exponential parametrization of the two-point correlation function of gluonic field strengths, the quark condensate does not depend on the non-confining non-perturbative interactions of the stochastic background Yang–Mills fields.

Description:    A measurement of the integrated luminosity at the ep collider HERA is presented, exploiting the elastic QED Compton process ep → eγp . The electron and the photon are detected in the backward calorimeter of the H1 experiment. The integrated luminosity of the data recorded in 2003 to 2007 is determined with a precision of 2.3 %. The measurement is found to be compatible with the corresponding result obtained using the Bethe–Heitler process.

Description:    A combination of the inclusive diffractive cross section measurements made by the H1 and ZEUS Collaborations at HERA is presented. The analysis uses samples of diffractive deep inelastic ep scattering data at a centre-of-mass energy where leading protons are detected by dedicated spectrometers. Correlations of systematic uncertainties are taken into account, resulting in an improved precision of the cross section measurement which reaches 6 % for the most precise points. The combined data cover the range 2.5〈 Q 2 〈200 GeV 2 in photon virtuality, in proton fractional momentum loss, 0.09〈| t |〈0.55 GeV 2 in squared four-momentum transfer at the proton vertex and 0.0018〈 β 〈0.816 in , where x is the Bjorken scaling variable.

Description:    The pMSSM provides a broad perspective on SUSY phenomenology. In this paper we generate two new, very large, sets of pMSSM models with sparticle masses extending up to 4 TeV, where the lightest supersymmetric particle (LSP) is either a neutralino or gravitino. The existence of a gravitino LSP necessitates a detailed study of its cosmological effects and we find that Big Bang Nucleosynthesis places strong constraints on this scenario. Both sets are subjected to a global set of theoretical, observational and experimental constraints resulting in a sample of ∼225k viable models for each LSP type. The characteristics of these two model sets are briefly compared. We confront the neutralino LSP model set with searches for SUSY at the 7 TeV LHC using both the missing (MET) and non-missing E T ATLAS analyses. In the MET case, we employ Monte Carlo estimates of the ratios of the SM backgrounds at 7 and 8 TeV to rescale the 7 TeV data-driven ATLAS backgrounds to 8 TeV. This allows us to determine the pMSSM parameter space coverage for this collision energy. We find that an integrated luminosity of ∼5–20 fb −1 at 8 TeV would yield a substantial increase in this coverage compared to that at 7 TeV and can probe roughly half of the model set. If the pMSSM is not discovered during the 8 TeV run, then our model set will be essentially void of gluinos and lightest first and second generation squarks that are ≲700–800 GeV, which is much less than the analogous mSUGRA bound. Finally, we demonstrate that non-MET SUSY searches continue to play an important role in exploring the pMSSM parameter space. These two pMSSM model sets can be used as the basis for investigations for years to come.

Description:    In the context of strongly coupled Electroweak Symmetry Breaking, composite light scalar singlet and composite triplet of heavy vectors may arise from an unspecified strong dynamics and the interactions among themselves and with the Standard Model gauge bosons and fermions can be described by a SU (2) L × SU (2) R / SU (2) L + R effective chiral Lagrangian. In this framework, the production of the V + V − and V 0 V 0 final states at the LHC by gluon fusion mechanism is studied in the region of parameter space consistent with the unitarity constraints in the elastic channel of longitudinal gauge boson scattering and in the inelastic scattering of two longitudinal Standard Model gauge bosons into Standard Model fermions pairs. The expected rates of same-sign di-lepton and tri-lepton events from the decay of the V 0 V 0 final state are computed and their corresponding backgrounds are estimated. It is of remarkable relevance that the V 0 V 0 final state can only be produced at the LHC via a gluon fusion mechanism since this state is absent in the Drell–Yan process. It is also found that the V + V − final-state production cross section via gluon fusion mechanism is comparable with the V + V − Drell–Yan production cross section. The comparison of the V 0 V 0 and V + V − total cross sections will be crucial for distinguishing the different models since the vector pair production is sensitive to many couplings. This will also be useful to determine if the heavy vectors are only composite vectors or are gauge vectors of a spontaneously broken gauge symmetry.

Description:    A search for a fermiophobic Higgs boson using diphoton events produced in proton-proton collisions at a centre-of-mass energy of is performed using data corresponding to an integrated luminosity of 4.9 fb −1 collected by the ATLAS experiment at the Large Hadron Collider. A specific benchmark model is considered where all the fermion couplings to the Higgs boson are set to zero and the bosonic couplings are kept at the Standard Model values (fermiophobic Higgs model). The largest excess with respect to the background-only hypothesis is found at 125.5 GeV, with a local significance of 2.9 standard deviations, which reduces to 1.6 standard deviations when taking into account the look-elsewhere effect. The data exclude the fermiophobic Higgs model in the ranges 110.0–118.0 GeV and 119.5–121.0 GeV at 95 % confidence level.

Description:    We present O ( α s ) results on the decays of polarized W ± and Z bosons into massive quark pairs. The NLO QCD corrections to the polarized decay functions are given up to the second order in the quark mass expansion. We find a surprisingly strong dependence of the NLO polarized decay functions on finite quark mass effects even at the relatively large mass scale of the W ± and Z bosons. As a main application we consider the decay t → b + W + involving the helicity fractions ρ mm of the W + boson followed by the polarized decay for which we determine the O ( α s ) polar angle decay distribution. We also discuss NLO polarization effects in the production/decay process .

Description:    The metal-insulator transition for the square, simple cubic, and body centered cubic lattices has been studied within the Hubbard model at half-filling taking into account nearest- and next-nearest-neighbor electron hopping. Both staggered antiferromagnetic and incommensurate magnetic states (spin-spiral wave) have been considered. The inclusion of the latter states for the three-dimensional lattices does not change the general pattern of the metal-insulator transition, but opens the fundamentally new possibility of the metal-insulator transition of the first order between the magnetically ordered states for the square lattice.

Description:    Precision measurements of the real and imaginary parts of the microwave surface impedance Z ac ( T ) = R ac ( T ) + iX ac ( T ) of the conducting ac layers of the k -(BEDT-TTF) 2 Cu[N(CN) 2 ]Br crystals in the temperature interval of 0.5 〈 T 〈 100 K have demonstrated a series of features: (i) the temperature course of the field penetration depth is close to linear Δλ ac ( T )∞Δ X ac ( T ) in the superconducting state at T T c ∼ 11.5 K; (ii) the curves R ac ( T ) = X ac ( T ) coincide at T c 〈 T 〈 40 K; (iii) the X ac ( T ) value at T 〉 40 K increases in comparison with R ac ( T ); (iv) the dependence R ac ( T ) at T 〉 40 K is nonmonotonic in thin crystals. These features of the impedance Z ac ( T ) with increasing T are interpreted in terms of (i) the d -type symmetry of the superconducting order parameter, (ii) normal skin effect, (iii) manifestations of the antiferromagnetic fluctuations, and (iv) the size effect. The electrodynamic parameters of k -(BEDT-TTF) 2 Cu[N(CN) 2 ]Br have been determined. Content Type Journal Article Category Condensed Matter Pages 184-187 DOI 10.1134/S0021364012150088 Authors N. V.

Description:    The experimental conditions that facilitate the excitation of parametric decay instabilities upon the electron cyclotron resonance heating of a plasma at the second harmonic extraordinary wave in tokamaks and stellarators and, as a result, make anomalous absorption of microwave power possible have been analyzed. It has been shown that, in the case of a nonmonotonic radial profile of the plasma density, when the beam of electron cyclotron waves passes near the equatorial plane of a toroidal device, the parametric excitation of electron Bernstein waves, as well as the generation of ion Bernstein waves propagating from the parametric decay region to the nearest ion cyclotron harmonic, where they efficiently interact with ions, is possible. The proposed theoretical model can explain the anomalous generation of accelerated ions observed upon electron cyclotron heating in small and moderate toroidal facilities.
