Nonequilibrium Effects of Anisotropic Compression Applied to Vortex Lattices in Bose-Einstein Condensates

September 1, 2002

Author(s)

P Engels, Ian R. Coddington, P C. Haljan, Eric A. Cornell

We have studied the dynamics of large vortex lattices in a dilute-gas Bose-Einstein condensate. While undisturbed lattices have a regularhexagonal structure, large-amplitude quadrupolar shape oscillations of the condensate are shown to induce a wealth of

Driving Bose-Einstein-Condensate Vorticity With a Rotating Normal Cloud

November 1, 2001

Author(s)

P C. Haljan, Ian R. Coddington, P Engels, Eric A. Cornell

We have developed an evaporative cooling technique that accelerates the circulation of an ultra-cold 87Rb gas, confined in a static harmonicpotential. As a normal gas is evaporatively spun up and cooled below quantum degeneracy, it is found to nucleate

Use of Surface-Wave Spectroscopy to Characterize Tilt Modes of a Vortex in a Bose-Einstein Condensate

April 1, 2001

Author(s)

P C. Haljan, B P. Anderson, Ian R. Coddington, Eric A. Cornell

A vortex in a condensate in a nonspherical trapping potential will in general experience a torque. The torque will induce tilting of the direction of the vortex axis. We observe this behavior experimentally and show that by applying small distortions to
