Topological Fulde-Ferrell superfluids in triangular lattices
Source PublicationPHYSICAL REVIEW A
Language英语
AbstractFulde-Ferrell (FF) Larkin-Ovchinnikov (LO) phases were proposed for superconductors or superfluids in a strong magnetic field. With the experimental progress in ultracold atomic systems, topological FFLO phases have also been put forward since it is a natural consequence of realizable spin-orbital coupling (SOC). In this paper, we theoretically investigate a triangular lattice model with SOC and an in-plane field. By constructing the phase diagram, we show that it produces gapped and gapless topological FF phases with Chern numbers C = +/- 1, +/- 2, +/- 3, and +/- 4. We get the phase boundaries by the change in the sign of the Pfaffian. The chiral edge states for different topological FF phases also are elucidated.
