Optical Visibility and Core Structure of Vortex Filaments in a Bosonic Superfluid
- 1. INO-CNR BEC Center and Dipartimento di Fisica, Universitä di Trento (Italy)
Description
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.
