Topological Phase Separation In Trapped Ultracold Fermionic Gases
arXiv:1106.0453 · doi:10.1088/0953-4075/45/6/065301
Abstract
We investigate the harmonically trapped 2D fermionic systems with a effective spin-orbit coupling and intrinsic s-wave superfluidity under the local density approximation, and find that there is a critical value for Zeeman field. When the Zeeman field larger than the critical value, the topological superfluid phases emerge and coexist with the normal superfluid phase, topological phase separation, in the trapped region. Otherwise, the superfluid phase is topologically trivial.
