Asymmetric Fermi Superfluid With Two Types Of Pairings

Abstract

We investigate the phase diagram in the plane of temperature and chemical potential mismatch for an asymmetric fermion superfluid with double- and single-species pairings. There is no mixing of these two types of pairings at fixed chemical potential, but the introduction of the single species pairing cures the magnetic instability at low temperature.Comment: 6 pages, 1 figure.
