Phys. Rev. A 62, 033607 (2000) [6 pages]Spinning up and down a Boltzmann gasReceived 2 March 2000; revised 27 April 2000; published 14 August 2000 Using the average method, we derive a closed set of linear equations that describes the spinning up of an harmonically trapped gas by a rotating anisotropy. We find explicit expressions for the time needed to transfer angular momentum as well as the decay time induced by a static residual anisotropy. These different time scales are compared with the measured nucleation time and lifetime of vortices by Madison et al. We find a good agreement that may emphasize the role played by the noncondensed component in those experiments. © 2000 The American Physical Society URL:
