Decay of quantised vorticity by sound emission
arXiv:cond-mat/0405635 · doi:10.1007/s10909-005-2272-5
Abstract
It is thought that in a quantum fluid sound generation is the ultimate sink of turbulent kinetic energy in the absence of any other dissipation mechanism near absolute zero. We show that a suitably trapped Bose-Einstein condensate provides a model system to study the sound emitted by accelerating vortices in a controlled way.
