Superfluid-to-Solid Crossover in a Rotating Bose-Einstein Condensate

November 1, 2001
Author(s)
D L. Feder, Charles W. Clark
The properties of a rotating Bose-Einstein condensate confined in a prolate cylindrically symmetric trap are explored both analytically and numerically. As the rotation frequency increases, an ever greater number of vortices are energetically favored

Volume Visualization of Bose-Einstein Condensates

April 1, 2001
Author(s)
Peter M. Ketcham, D L. Feder, Charles W. Clark, Steven G. Satterfield, Terence J. Griffin, William L. George, Barry I. Schneider, W P. Reinhardt
Theoretical aspects of Bose-Einstein condensates are investigated by conducting computer simulations of their behavior. Scientific visualization techniques are employed in order to examine the large amount of data generated by simulation. Visualization of

Watching Dark Solitons Decay Into Vortex Rings in a Bose-Einstein Condensate

April 1, 2001
Author(s)
B P. Anderson, P C. Haljan, C A. Regal, D L. Feder, L A. Collins, Charles W. Clark
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 filled with the second component. The filled solitons are stable for hundreds of

An obituary of Ugo Fano (1212-2001), member of the National Bureau of Standards staff from 1946 to 1966.

Anomalous Modes Underpin Vortex Dynamics in Confined Bose-Einstein Condensates

January 1, 2001
Author(s)
D L. Feder, A A. Svidzinsky, A L. Fetter, Charles W. Clark
The dynamics of vortices in trapped Bose-Einstein condensates are investigated both analytically and numerically. In axially symmetric traps, the critical rotation frequency for metasability of an isolated vortex coincides with the largest vortex
