Singlet and Triplet Superfluid Competition in a Mixture of Two-Component Fermi and One-Component Dipolar Bose Gases

摘要

We consider a mixture of two-component Fermi and (one-component) dipolar Bosegases in which both dipolar interaction and s-wave scattering between fermionsof opposite spins are tunable. We show that in the long wavelength limit, theanisotropy in the Fermi-Fermi interaction induced by phonons of the dipolarcondensate can strongly enhance the scattering in the triplet channel. Weinvestigate in detail the conditions for achieving optimal critical temperatureat which the triplet superfluid begins to compete with the singlet superfluid.
