Bose-Einstein condensates with localized spin-orbit coupling: Soliton complexes and spinor dynamics
Spin-orbit (SO) coupling can be introduced in a Bose--Einstein condensate (BEC) as a gauge potential acting only in a localized spatial domain. Effect of such a SO "defect" can be understood by transforming the system to the integrable vector model. The properties of the SO-BEC change drastically if the SO …
