Dissipation and Vortex Creation in Bose-Einstein Condensed Gases
arXiv:cond-mat/9912365 · doi:10.1103/PhysRevA.61.051603
Abstract
We solve the Gross-Pitaevskii equation to study energy transfer from an oscillating `object' to a trapped Bose-Einstein condensate. Two regimes are found: for object velocities below a critical value, energy is transferred by excitation of phonons at the motion extrema; while above the critical velocity, energy transfer is via vortex formation. The second regime corresponds to significantly enhanced heating, in agreement with a recent experiment.
