We consider a weakly interacting two-component Fermi gas of dipolar particles (magnetic atoms or polar molecules) in two-dimensional geometry. The dipole-dipole interaction (together with the short-range interaction at Feshbach resonances) for dipoles perpendicular to the plane of translational motion may provide a superfluid transition. The dipole-dipole scattering amplitude is momentum dependent, which violates the Anderson theorem that claims the independence of the transition temperature on the presence of weak disorder. We have shown that the disorder can strongly increase the critical temperature (up to $10\mathrm{nK}$ at realistic densities). This opens wide possibilities for the studies of the superfluid regime in weakly interacting Fermi gases, which has not been observed so far.

无序偶极费米气体中的超流体跃迁

我们考虑二维几何结构中偶极子粒子（磁性原子或极性分子）的弱相互作用两组分费米气体。垂直于平移运动平面的偶极子的偶极子-偶极子相互作用（以及在Feshbach共振处的短程相互作用）可能会提供超流体跃迁。偶极子-偶极子的散射幅度是动量相关的，这违反了安德森定理，该定理要求在存在弱无序时转变温度是独立的。我们已经表明，这种疾病会极大地提高临界温度（最高$10\mathrm{nK}$以现实的密度）。这为研究弱相互作用费米气体中的超流体状态开辟了广阔的可能性，迄今为止尚未观察到。
