Collective excitations of degenerate Fermi gases in anisotropic parabolic traps
arXiv:cond-mat/0007049 · doi:10.1103/PhysRevA.63.013606
Abstract
The hydrodynamic low-frequency oscillations of highly degenerate Fermi gases trapped in anisotropic harmonic potentials are investigated. Despite the lack of an obvious spatial symmetry the wave-equation turns out to be separable in elliptical coordinates, similar to a corresponding result established earlier for Bose-condensates. This result is used to give the analytical solution of the anisotropic wave equation for the hydrodynamic modes.
