Vortex proliferation in the Berezinskii-Kosterlitz-Thouless regime on a two-dimensional lattice of Bose-Einstein condensates
V. Schweikhard, S. Tung, E. A. Cornell
We observe the proliferation of vortices in the Berezinskii-Kosterlitz-Thouless regime on a two-dimensional array of Josephson-coupled Bose-Einstein condensates. As long as the Jos…
Observation of Vortex Pinning in Bose-Einstein Condensates
S. Tung, V. Schweikhard, E. A. Cornell
We report the observation of vortex pinning in rotating gaseous Bose-Einstein condensates (BEC). The vortices are pinned to columnar pinning sites created by a co-rotating optical…
On Dispersive and Classical Shock Waves in Bose-Einstein Condensates and Gas Dynamics
M. A. Hoefer, M. J. Ablowitz, I. Coddington +3
A Bose-Einstein condensate (BEC) is a quantum fluid that gives rise to interesting shock wave nonlinear dynamics. Experiments depict a BEC that exhibits behavior similar to that of…
Vortex Lattice Dynamics in Rotating Spinor Bose-Einstein Condensates
V. Schweikhard, I. Coddington, P. Engels +2
We observe interlaced square vortex lattices in rotating two-component dilute-gas Bose-Einstein condensates (BEC). After preparing a hexagonal vortex lattice in a single-component…
Observations on Sound Propagation in Rapidly Rotating Bose-Einstein Condensates
T. P. Simula, P. Engels, I. Coddington +3
Repulsive laser potential pulses applied to vortex lattices of rapidly rotating Bose-Einstein condensates create propagating density waves which we have observed experimentally and…
Experimental studies of equilibrium vortex properties in a Bose-condensed gas
I. Coddington, P. C. Haljan, P. Engels +3
We characterize several equilibrium vortex effects in a rotating Bose-Einstein condensate. Specifically we attempt precision measurements of vortex lattice spacing and the vortex c…
