Frequency and damping of hydrodynamic modes in a trapped Bose-condensed gas
Tetsuro Nikuni, Allan Griffin
Recently it was shown that the Landau-Khalatnikov two-fluid hydrodynamics describes the collision-dominated region of a trapped Bose condensate interacting with a thermal cloud. We…

Kinetic Theory of a Spin-1/2 Bose-Condensed Gas
T. Nikuni, J. E. Williams
We derive a kinetic theory for a spin-1/2 Bose-condensed gas of two-level atoms at finite temperatures. The condensate dynamics is described by a generalized Gross-Pitaevskii equat…

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…
