Stability of a single vortex in a trapped Bose-Einstein condensate

Kavoulakis, Georgios LU (2005) In European Physical Journal D. Atomic, Molecular, Optical and Plasma Physics 36(1). p.11-15
Abstract
We investigate the lowest state of a Bose-Einstein condensate with an off-center vortex state that is confined in a rotating harmonic potential. Our results are consistent with the fact that any single off-center vortex is unstable. Furthermore, a vortex state located at the center of the cloud first becomes locally stable as the rotational frequency increases. Finally our study implies the existence of hysteresis effects.
