Critical temperature and phase diagram for a 2D superfluid Fermi-gas with repulsion
Abstract
In the framework of a 2D Fermi-gas with short-range repulsive interaction we find the critical temperature of the superfluid phase transition based on Kohn-Luttinger effect, and analyze its dependence on magnetic field. We calculate strong-coupling corrections to the Ginzburg-Landau free energy functional and analyze the staibility of 2D superfluid phases. Possible applications of the results to real systems are discussed.
