Topological superfluids in two-dimensional Fermi gas with Rashba spin-orbit coupling
Xiaosen Yang, Ho-Kin Tang, Noah Fan Qi Yuan +4
The realization of spin-orbit coupling (SOC) in ultracold atoms has triggered an intensive exploring of topological superfluids in the degenerate Fermi gases based on mean-field th…
Dynamical instability towards finite-momentum pairing in quenched BCS superconducting phases
Beibing Huang, Xiaosen Yang, Ning Xu +2
In this work we numerically investigate the fate of the Bardeen-Cooper-Schrieffer (BCS) pairing in the presence of quenched phase under Peierls substitution using time-dependent re…
Topological superfluids with time-reversal symmetry from -wave interaction in a bilayer system
Beibing Huang, Pak Hong Chui, Jia Liu +2
Topological superconducting phases with time-reversal (TR) symmetry have been widely explored in recent years. However the involved unconventional pairings are generally implausibl…

Beibing Huang, Xiaosen Yang, Shaolong Wan
To realize non-Abelian s-wave topological superfluid (TS) of cold Fermi gases, generally a Zeeman magnetic field larger than superfluid pairing gap is necessary. In this paper we f…
