论文摘要
我们研究了弱障碍对两组分量二维偶极费米气体的超流体特性的影响。偶极 - 偶极相互作用幅度取决于动量，这违反了Anderson定理，声称该弱体障碍实际上对弱相互作用的状态中的超流体过渡温度没有影响。我们发现，对于偶性费米子，这种疾病可以像纯粹的二维情况一样大大提高该状态的过渡温度。然而，随着互动相互作用的相互作用的增加，效果变得较小，在强烈相互作用的方向上，弱混乱症中的超流体过渡温度在没有疾病的情况下变得非常接近。
We investigate the effect of weak disorder on the superfluid properties of two-component quasi-two-dimensional dipolar Fermi gases. The dipole-dipole interaction amplitude is momentum dependent, which violates the Anderson theorem claiming that the weak disorder has practically no influence on the superfluid transition temperature in the weakly interacting regime. We find that for dipolar fermions the transition temperature in this regime can be strongly increased by the disorder like in the purely two-dimensional case. However, the effect becomes smaller with increasing the intercomponent fermion-fermion interaction, and in the strongly interacting regime the superfluid transition temperature in the weak disorder becomes very close to that in the absence of disorder.
