Anisotropic Fermi Superfluid via p-wave Feshbach Resonance

Abstract

We investigate theoretically Fermionic superfluidity induced by Feshbach resonance in the orbital p-wave channel. We show that, 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 $\hat{z}$, 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.
