Critical velocity in cylindrical Bose-Einstein condensates
Abstract
We describe a dramatic decrease of the critical velocity in elongated cylindrical Bose-Einstein condensates which originates from the nonuniform character of the radial density profile. We discuss this mechanism with respect to recent measurements at MIT.
