Vortex pairs in a spin-orbit-coupled Bose-Einstein condensate
Vortex pairs in a spin-orbit-coupled Bose-Einstein condensate
Static and dynamic properties of vortices in a two-component Bose-Einstein condensate with Rashba spin-orbit coupling are investigated. The mass current around a vortex core in the plane-wave phase is found to be deformed by the spin-orbit coupling, and this makes the dynamics of the vortex pairs quite different from those …
