Nonequilibrium effects of anisotropic compression applied to vortex lattices in Bose-Einstein condensates
P. Engels, I. Coddington, P. C. Haljan +1
We have studied the dynamics of large vortex lattices in a dilute-gas Bose-Einstein condensate. While undisturbed lattices have a regular hexagonal structure, large-amplitude quadr…
Watching dark solitons decay into vortex rings in a Bose-Einstein condensate
B. P. Anderson, P. C. Haljan, C. A. Regal +4
We have created spatial dark solitons in two-component Bose-Einstein condensates in which the soliton exists in one of the condensate components and the soliton nodal plane is fill…
Vortices in a Bose-Einstein Condensate
M. R. Matthews, B. P. Anderson, P. C. Haljan +3
We have created vortices in two-component Bose-Einstein condensates. The vortex state was created through a coherent process involving the spatial and temporal control of interconv…
Watching a superfluid untwist itself: Recurrence of Rabi oscillations in a Bose-Einstein condensate
M. R. Matthews, B. P. Anderson, P. C. Haljan +5
The order parameter of a condensate with two internal states can continuously distort in such a way as to remove twists that have been imposed along its length. We observe this eff…
