Abstract

An attempt was made to prove the surprising fact that a weakly interacting condensate in a stationary trap cannot host stable persistent currents of well defined vorticity, showing that the nonlinearity is essential to sustain vortices. For this purpose, a dilute gaseous Bose-Einstein condensate (BEC) in the zero-temperature limit was studied. The mechanism for the structural destabilization of vortices was shown and a way to verify this prediction in current experiments was proposed.
