Interferometric detection of a single vortex in a dilute Bose-Einstein condensate
arXiv:cond-mat/0104545 · doi:10.1103/PhysRevA.64.031601
Abstract
Using two radio frequency pulses separated in time we perform an amplitude division interference experiment on a rubidium Bose-Einstein condensate. The presence of a quantized vortex, which is nucleated by stirring the condensate with a laser beam, is revealed by a dislocation in the fringe pattern.
