Abstract

We investigate the thermal instability of a Bose-Einstein condensate stirred by a rotating barrier in a ring-shaped trap. One would expect the critical angular speed to decrease with increasing temperature due to depletion of the condensate. However, we show that the critical velocity remains approximately constant within a considerable range of temperatures, contrary to expectation, and the thermal cloud has a stabilizing effect.
