Finite Temperature Phase Diagram of a Two-Component Fermi Gas with Density Imbalance

, 2006
We investigated possible superfluid phases at finite temperature in a two-component Fermi gas with density imbalance. In the frame of a general four-fermion interaction theory, we solved in the BCS region the gap equations for the pairing gap and pairing
