我们提供了强有力的证据，最近的观察M。格雷纳角Regal和D. Jin和麻省理工学院的研究小组是由大的费米子对组成的强相互作用体系中的费米子超流体的特征。我们的结论是基于使用交叉理论计算不同的潜力，包括那些具有双通道模型的特点。我们的结果清楚地表明共振附近的普遍性。用交叉理论预测的T_{c}$与观测到的凝结分数消失边界完全吻合，不需要任何可调参数。
We offer strong evidence that the recent observations by M. Greiner, C. Regal, and D. Jin and by MIT group are signatures of a fermion superfluid in the strongly interacting regime made up of large fermion pairs. Our conclusions are based on calculations using crossover theory for different potentials including those with the characteristics of two-channel models. Our results demonstrate clearly universality near resonance. The $T_{c}$ predicted by crossover theory is a perfect match with the observed boundary of vanishing condensate fraction with no adjustable parameters.
