We investigate unconventional superfluidity in a gas of Fermi atoms with an anisotropic p-wave Feshbach resonance. Including the p-wave Feshbach resonance as well as the associated three kinds of quasimolecules with finite orbital angular momenta Lz=+/-1,0, we calculate the transition temperature of the superfluid phase. As one passes through the p-wave Feshbach resonance, we find the usual BCS-BEC crossover phenomenon. The p-wave BCS state continuously changes into the BEC of bound molecules with L=1. Our calculation includes the effect of fluctuations associated with Cooper pairs and molecules which are not Bose condensed.
我们研究了具有各向异性p波费什巴赫共振的费米原子气体中的非常规超流性。包括p波费什巴赫共振以及与之相关的三种具有有限轨道角动量Lz = ±1、0的准分子，我们计算了超流相的转变温度。当通过p波费什巴赫共振时，我们发现了常见的BCS - BEC交叉现象。p波BCS态连续转变为L = 1的束缚分子的BEC态。我们的计算包括了与未发生玻色凝聚的库珀对和分子相关的涨落效应。
