我们研究了自旋极化费米气体在宽费什巴赫共振附近具有自旋轨道耦合的相分离。由于自旋轨道耦合和布居不平衡之间的竞争，均匀气体的相图发展出丰富的相分离结构，涉及拓扑上非平凡的无间隙超流体态。然后，我们演示了由外部捕获电势引起的相分离，并讨论了无间隙超流体相实验观察的最佳参数区域。
We study the phase separation of a spin-polarized Fermi gas with spin-orbit coupling near a wide Feshbach resonance. As a result of the competition between spin-orbit coupling and population imbalance, the phase diagram for a uniform gas develops a rich structure of phase separation involving topologically nontrivial gapless superfluid states. We then demonstrate the phase separation induced by an external trapping potential and discuss the optimal parameter region for the experimental observation of the gapless superfluid phases.
