Publication Date: 2012-11-13

Description: Author(s): S. Modak, K. Sengupta, and Diptiman Sen We study a junction of a topological insulator with a thin two-dimensional nonmagnetic or partially polarized ferromagnetic metallic film deposited on a three-dimensional insulator. We show, by deriving generic boundary conditions applicable to electrons traversing the junction, that there is a fini... [Phys. Rev. B 86, 205114] Published Mon Nov 12, 2012

Description: Author(s): Rajdeep M. Chatterjee, Monoranjan Guchait, and Dipan Sengupta We have revisited the prospects of supersymmetry searches at the LHC with 7 TeV energy along with the prediction of the discovery potential at 8 TeV energy assuming an integrated luminosity 5 fb -1 and 20 fb -1 with minimal supergravity/minimal supersymmetric standard model as a model framework. We ... [Phys. Rev. D 86, 075014] Published Wed Oct 10, 2012

Publication Date: 2012-08-25

Description: Author(s): Anirban Dutta, C. Trefzger, and K. Sengupta We develop a projection operator formalism for studying both the zero-temperature equilibrium phase diagram and the nonequilibrium dynamics of the Bose-Hubbard model. Our work, which constitutes an extension of that of Trefzger and Sengupta [ Phys. Rev. Lett. 106 095702 (2011) ], shows that the meth... [Phys. Rev. B 86, 085140] Published Fri Aug 24, 2012

Description: Author(s): Diptimoy Ghosh, Monoranjan Guchait, Sreerup Raychaudhuri, and Dipan Sengupta We study the allowed parameter space of the constrained minimal supersymmetric Standard Model (cMSSM) in the light of direct searches, constraints from B -physics (including the recent measurement of the branching ratio for B s → μ + μ - ) and the dark matter relic density. For low or moderate values of tan... [Phys. Rev. D 86, 055007] Published Mon Sep 10, 2012

Description: Author(s): G. Seyfarth, A.-S. Rüetschi, K. Sengupta, A. Georges, D. Jaccard, S. Watanabe, and K. Miyake The first heavy fermion superconductor CeCu 2 Si 2 has not revealed all its striking mysteries yet. At high pressures, superconductivity is supposed to be mediated by valence fluctuations, in contrast to ambient pressure, where spin fluctuations most likely act as pairing glue. We have carried out a mu... [Phys. Rev. B 85, 205105] Published Thu May 03, 2012

Description: Author(s): Monoranjan Guchait, D. P. Roy, and Dipan Sengupta We have analyzed the prospect of probing a nonuniversal gaugino mass model of mixed bino-Higgsino dark matter at the current 7 TeV run of LHC. It provides cosmologically compatible dark matter relic density over two broad bands of parameters, corresponding to m g ˜ 〈 m q ˜ and m g ˜ ∼ m q ˜ . The supersymmetr... [Phys. Rev.

Publication Date: 2011-09-14

Description: Author(s): Monoranjan Guchait and Dipan Sengupta We investigate the prospects of supersymmetry searches at the LHC with 7 TeV energy. A new set of selection cuts is proposed based on event shapes to control backgrounds. Our preliminary studies show that it is possible to minimize backgrounds to a significantly low level and a conservative estimate... [Phys. Rev. D 84, 055010] Published Tue Sep 13, 2011

Description: Author(s): I. Paul, A. Cano, and K.

We study the effects of magnetoelastic couplings on this transition using symmetry considerations. We find that the magnetic order parameters ar... [Phys. Rev.
