Collisional Properties of a Polarized Fermi Gas with Resonant Interactions
arXiv:0804.1885 · doi:10.1103/PhysRevLett.100.240406
Abstract
Highly polarized mixtures of atomic Fermi gases constitute a novel Fermi liquid. We demonstrate how information on thermodynamic properties may be used to calculate quasiparticle scattering amplitudes even when the interaction is resonant and apply the results to evaluate the damping of the spin dipole mode. We estimate that under current experimental conditions, the mode would be intermediate between the hydrodynamic and collisionless limits.
