Scissors modes of two-component degenerate gases: Bose-Bose and Bose-Fermi mixtures
arXiv:cond-mat/0310498 · doi:10.1103/PhysRevA.69.023617
Abstract
We investigate the scissors modes in binary mixtures of degenerate dilute quantum gases, for both Bose-Bose and Bose-Fermi mixtures. For the latter we consider both the superfluid and normal hydrodynamic and collisionless regimes. We analyze the dependence of the frequencies of the scissors modes and their character as a function of the Bose-Fermi coupling and the trap geometry. We show that the scissors mode can reveal a clear trace of the hydrodynamic behavior of the Fermi gas.
