Superfluid transition temperature in a dilute Bose–Fermi mixture with imbalanced two-component Fermi gas

摘要

We study s- and p-wave pairing of population imbalanced Fermi atoms in a dilute Bose–Fermi mixture.s-wave pairing takes place only between atoms of different spins, while p-wave Cooper pair is formed by atoms in the same spin component. We calculate the transition temperature of this system in the presence of all interactions between two-spin states. The effective interaction between two-spin states is the sum of the direct one gFF, the one arising from polarization of the bosonic medium gFBF and that due to polarization of the fermionic medium itself gFFF. The p-wave channel can exist due to polarization of the bosonic medium with the effective attractive interaction and we estimate of the transition temperature increase due to this effect.
