Critical velocity in cylindrical Bose-Einstein condensates
arXiv:cond-mat/0004039 · doi:10.1103/PhysRevA.63.045601
Abstract
We describe a dramatic decrease of the critical velocity in elongated cylindrical Bose-Einstein condensates which originates from the non-uniform character of the radial density profile. We discuss this mechanism with respect to recent measurements at MIT.
