Increase in superfluid transition temperature in polarized Fermi gas with repulsion
Kagan M. Yu. , Chubukov A. V.
A magnetic field can intensify the Kohn-Luttinger effect, i.e., can lead to a substantial increase in the temperature of Ρ pairing in a low-density Fermi gas with repulsion. The temperature Tc goes through a maximum at a degree of polarization a = 0.48. The two-dimensional case has also been studied.
