Vortex lines and vortex lattices in a Bose-Einstein condensate

摘要

Since the advent of Bose-Einstein condensates (BEC) in the dilute alkalis, there has been considerable interest in observing effects in atomic BEC akin to the hallmark effects associated with a superfluid. A particularly striking evidence for superfluidity is the appearance of quantized vortices in a BEC under the influence of an external, rotating environment.
