Abstract
Understanding the relationship between Bose-Einstein condensation (BEC)
and superfluidity has been central to low temperature research
over much of the past century. Yet a quantitative study of this
important issue has only recently become possible with the achievement
of
BEC in trapped atomic gases. The superfluidity of these dilute,
weakly interacting Bose gases has been strikingly confirmed by the recent
observation of quantized vortices in condensates at JILA(Colorado)
and the ENS(Paris). I will discuss issues involved in the formation,
stability, and dynamics of vortices in these new mesoscopic systems.
