Observations on Sound Propagation in Rapidly Rotating Bose-Einstein Condensates
arXiv:cond-mat/0407343 · doi:10.1103/PhysRevLett.94.080404
Abstract
Repulsive laser potential pulses applied to vortex lattices of rapidly rotating Bose-Einstein condensates create propagating density waves which we have observed experimentally and modeled computationally to high accuracy. We have observed a rich variety of dynamical phenomena ranging from interference effects and shock-wave formation to anisotropic sound propagation.
