Low-lying excitation modes of trapped dipolar Fermi gases: From the collisionless to the hydrodynamic regime
Low-lying excitation modes of trapped dipolar Fermi gases: From the collisionless to the hydrodynamic regime
By means of the Boltzmann-Vlasov kinetic equation we investigate dynamical properties of a trapped one-component Fermi gas at zero temperature, featuring the anisotropic and long-range dipole-dipole interaction. To this end, we determine an approximate solution by rescaling both space and momentum variables of the equilibrium distribution, thereby obtaining coupled ordinary …
