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.

Notes

ACKNOWLEDGMENTS

We dedicate this paper to L.P. Pitaevskii in celebration of his 85th birthday. No words can express our gratitude for the times spent working alongside him and, of course, for his pioneering contributions to physics itself. This work is supported by Provincia Autonoma di Trento and by QuantERA ERA-NET cofund project NAQUAS.
