On the detection of condensate vortex states
arXiv:cond-mat/9712130 · doi:10.1103/PhysRevA.58.576
Abstract
We discuss a detection scheme that reveals the existence of vortex states in a cylindrically symmetric condensate trap. It relies on the measurement of the second-order correlation function of the Schrödinger field, and yields directly the topological charge of the vortex state.
