Topological phase transitions on a triangular optical lattice with non-Abelian gauge fields
arXiv:1601.01185 · doi:10.1103/PhysRevA.93.033632
Abstract
We study the mean-field BCS-BEC evolution of a uniform Fermi gas on a single-band triangular lattice, and construct its ground-state phase diagrams, showing a wealth of topological quantum phase transitions between gapped and gapless superfluids that are induced by the interplay of an out-of-plane Zeeman field and a generic non-Abelian gauge field.
