Abstract
In the framework of a 2D Fermi gas with short-range repulsive interaction w e find the critical temperature of the superfluid phase transition based on Kohn-Luttinger effect, and analyze its dependence on magnetic field. We ca lculate strong coupling corrections to the Ginzburg-Landau free energy func tional and analyze the stability of 2D Superfluid phases. Possible applicat ions of the results to real systems are discussed. (C) 2000 Elsevier Scienc e B.V. All rights reserved.
