Spin-Orbit Coupling in Quantum Gases


Light-induced synthetic gauge field in ultracold quantum gases has received tremendous attention over the past few years. In the case of a non-Abelian gauge field, the internal pseudo-spin degrees of freedom and the motional degrees of freedom of the cold atom are coupled. Such spin-orbit coupling dramatically modifies the (single-body, few-body, and many-body) properties of the atomic system. I will briefly review the experimental status of spin-orbit coupled quantum gases and then focus on recent theoretical works from our group.
