Spin excitations in fermion condensates
arXiv:cond-mat/0503111
Abstract
We investigate collective spin excitations in two-component fermion condensates with special consideration of unequal populations of the two components. The frequencies of monopole and dipole modes are calculated using Thomas-Fermi theory and the scaling approximation. We demonstrate that spin oscillations have more sensitivity to the interaction and the properties of the condensates than the density oscillations.
