Density Oscillations in Trapped Bose Condensates at Finite Temperatureose gas above the phase transition are analysed in linear response theory. Their complex velocity of sound is determined, finding a pure relaxation-mode for weak interactions. Then we consider the coupled dynamics of a condensate interacting with the density of non-condensed atoms, and determine num

Coherent Vortex Dynamics in Two- and Three-Dimensional Bose-Einstein Condensatesld have a 2π phase circulation about a point of zero amplitude, and thus allow circulating flow in the (otherwise) irrotational quantum fluid. A classic experiment in superfluidity demonstrated that vortices form as the preferred stable state in a rotating cylinder of He II [.], a result explained t

Quasicondensate Droplet Formation in Hydrogen stimulated studies of the formation and evolution of condensates [.]. The kinetics of the condensate formation from a nonequilibrium initial state to a final coherent state has been explored in many systems [.], and particularly in dilute atomic gases [.],[.]. Recently, effects of quasicondensates
