Anisotropic Fermi superfluid via p-wave Feshbach resonance -: art. no. 070404

We investigate theoretically fermionic superfluidity induced by Feshbach resonance in the orbital p-wave channel and determine the general phase diagram. In contrast with superfluid He-3, due to the dipole interaction, the pairing is extremely anisotropic. When this dipole interaction is relatively strong, the pairing has symmetry k(z). When it is relatively weak, it is of symmetry k(z)+i beta k(y) (up to a rotation about (z) over cap, here beta < 1). A phase transition between these two states can occur under a change in the magnetic field or the density of the gas.
