    Trapped Bose condensate in a gravitational field (2000)
    Springer
    JETP letters 71 (2000), S. 266-270 
    Details
    ISSN: 1090-6487

    Notes: Abstract The Bose condensation of atoms in finite 1D and 2D parabolic traps placed in a gravitational field is considered. The distortion of the trap potential in this field is modeled by a combination of two rectangular 1D and 2D traps. The change in the critical temperature T c is found with regard to the cutoff and renormalization of the spectrum of these model potentials. The shift of the critical temperature T c in the gravitational field is calculated. The shift sign and magnitude depend on the way of introducing the gravitational field. For a certain choice, three critical temperatures can be sequentially observed. These temperatures can be attributed to three Bose condensations that occur in the cyclic motion of the trap along the Earth (I)-space (II)-Earth (III) route.

    Superfluid phase transition in trapped atomic Fermi gas (2000)
    Springer
    JETP letters 72 (2000), S. 385-392 
    Details
    ISSN: 1090-6487

    Topics: Physics
    Notes: Abstract Superfluid phase transition in an atomic Fermi gas confined to a harmonic trap is studied. The critical transition temperature and the temperature dependence and spatial shape of the order parameter are determined. The spectrum and wave functions of single-particle and collective excitations are obtained for a gas in the superfluid phase. The excitation eigenfrequencies exhibit a pronounced temperature dependence, allowing, e.g., identification of the superfluid phase.
