Manipulation of vortices by localized impurities in Bose-Einstein condensates
Manipulation of vortices by localized impurities in Bose-Einstein condensates
We consider the manipulation of Bose-Einstein condensate vortices by optical potentials generated by focused laser beams. It is shown that for appropriate choices of the laser strength and width it is possible to successfully transport vortices to various positions inside the trap confining the condensate atoms. Furthermore, the full bifurcation …
