Abstract
The effect of superfluidity on expansion of a rotating Bose-Einstein condensate was investigated. The time evolution of the expansion of condensate after its release from the confining trap was studied. The condensate was found to achieve a circular cross-section when the condensate was not initially rotating. The irrotational flow and the conservation of angular momentum when the condensate was initially rotating, prevented the released condensate from attaining a circular cross-section.
