An Optical Spoon Stirs Up Vortices in a Bose–Einstein Condensate
DOI: 10.1063/1.1310116
Since the early days of Bose–Einstein condensates (BECs) in atomic gases, comparisons have been drawn to the other familiar bosonic systems: liquid helium‐4 and the Cooper pairs of superconductors. Two of the early questions asked of BECs were whether they had similar coherence properties and whether they were superfluids. In
