Detection of vorticity in Bose-Einstein condensed gases by matter-wave interference
arXiv:cond-mat/9807345 · doi:10.1103/PhysRevLett.81.5477
Abstract
A phase-slip in the fringes of an interference pattern is an unmistakable characteristic of vorticity. We show dramatic two-dimensional simulations of interference between expanding condensate clouds with and without vorticity. In this way, vortices may be detected even when the core itself cannot be resolved.
