Optical visibility and core structure of vortex filaments in a bosonic superfluid
arXiv:1804.03017 · doi:10.1134/S1063776118110018
Abstract
We use optical images of a superfluid consisting of a weakly interacting Bose-Einstein condensate of sodium atoms to investigate the structure of quantized three-dimensional vortex filaments. We find that the measured optical contrast and the width of the vortex core quantitatively agree with the predictions of the Gross-Pitaevskii equation.
