Superfluid properties of one-component Fermi gas with an anisotropic p-wave interaction

Abstract

We investigate superfluid properties and strong-coupling effects in a one-component Fermi gas with an anisotropic p-wave interaction. Within the framework of the Gaussian fluctuation theory, we determine the superfluid transition temperature $T_{\mathrm{c}}$, as well as the temperature $T_0$ at which the phase transition from the $p_x$-wave pairing state to the $p_x+i{p}_y$-wave state occurs below $T_{\mathrm{c}}$. We also show that while the anisotropy of the p-wave interaction enhances $T_{\mathrm{c}}$ in the strong-coupling regime, it suppresses $T_0$.
