Gapless finite- theory of collective modes of a trapped gas
D. A. W. Hutchinson, R. J. Dodd, K. Burnett
We present predictions for the frequencies of collective modes of trapped Bose-condensed Rb atoms at finite temperature. Our treatment includes a self-consistent treatment o…

Collective excitations of atomic Bose-Einstein condensates
Mark Edwards, P. A. Ruprecht, K. Burnett +2
We apply linear-response analysis of the Gross-Pitaevskii equation to obtain the excitation frequencies of a Bose-Einstein condensate confined in a time-averaged orbiting potential…
