A hidden symmetry of collisionless sound of Bose condensates in anisotropic traps
arXiv:cond-mat/9805338 · doi:10.1103/PhysRevA.59.R27
Abstract
We derive a symmetry property for the Fourier-transform of the collisionless sound modes of Bose condensates in anisotropic traps connected with a somewhat hidden conservation law. We discuss its possible observation by dispersive light scattering.
