Direct observation of irrotational flow and evidence of superfluidity in a rotating Bose-Einstein condensate.
We have observed the expansion of vortex-free, rotating Bose condensates after their sudden release from a slowly rotating anisotropic trap. Conservation of angular momentum, combined with the constraint of irrotational flow, cause the rotating condensate to expand in a distinctively different way t...
