Superfluid pairing in a mixture of a spin-polarized Fermi gas and a dipolar condensate

摘要

A mixture of a spin-polarized Fermi gas and a dipolar Bose-Einstein condensate is considered in which s-wavenscattering between fermions and the quasiparticles of the dipolar condensate can result in an effective attractivenFermi-Fermi interaction long-range and anisotropic in nature and tunable by the dipolar interaction. It is shownnthat such an interaction can significantly increase the prospect of realizing a superfluid with a gap parameterncharacterized with a coherent superposition of all odd partial waves. In the spirit of the Hartree-Fock-Bogoliubovnmean-field approach, a theory is formulated that allows the estimation of the critical temperature when thenanisotropic Fock potential is taken into consideration and the determination of the system parameters thatnoptimize the critical temperature at which such a superfluid emerges before the system begins to phase separate.
