我们研究了具有种间和种内配对的不对称费米子超流体的相结构。在规范系综中引入种内配对机制显着改变了相图，并带来了种间和种内配对共存的新状态。与仅具有种间配对的情况不同，所有费米子激发在具有种内配对的区域中完全有间隙。
We investigate the phase structure of an asymmetric fermion superfluid with inter- and intra-species pairings. The introduction of the intra-species pairing mechanism in the canonical ensemble changes significantly the phase diagram and brings in a new state with coexisting inter- and intra-species pairings. Different from the case with only inter-species pairing, all the fermion excitations are fully gapped in the region with intra-species pairing.
