Transverse modes of a cigar-shaped Bose-Einstein condensate
B. Jackson, E. Zaremba
We discuss the collective modes in a harmonically trapped, highly-elongated Bose condensed gas. The transverse breathing mode exhibits a number of interesting features, such as the…

Dynamical Simulations of Trapped Bose Gases at Finite Temperatures
B. Jackson, E. Zaremba
In this paper, we develop a numerical procedure for investigating the dynamics of trapped Bose gases based on the ZGN theory. The dynamical equations used consist of a generalized…

Dynamics of trapped Bose gases at finite temperatures
E. Zaremba, T. Nikuni, A. Griffin
Starting from an approximate microscopic model of a trapped Bose-condensed gas at finite temperatures, we derive an equation of motion for the condensate wavefunction and a quantum…
