Vortex lattices in a stirred Bose-Einstein condensate
K. W. Madison, F. Chevy, W. Wohlleben +1
We stir with a focused laser beam a Bose-Einstein condensate of Rb atoms confined in a magnetic trap. We observe the formation of a single vortex for a stirring frequency ex…

Vortex formation in a stirred Bose-Einstein condensate
K. W. Madison, F. Chevy, W. Wohlleben +1
Using a focused laser beam we stir a Bose-Einstein condensate of 87Rb confined in a magnetic trap and observe the formation of a vortex for a stirring frequency exceeding a critica…
