Exploring quantum criticality based on ultracold atoms in optical lattices
Xibo Zhang, Chen-Lung Hung, Shih-Kuang Tung +2
Critical behavior developed near a quantum phase transition, interesting in its own right, offers exciting opportunities to explore the universality of strongly-correlated systems…
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…
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…
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…
