TL;DR: In this paper, the frequencies of collective oscillations of two-component Fermi gas that is kept on the repulsive branch of its energy spectrum were calculated, showing contributions from various gas excitations.
Abstract: We calculate frequencies of collective oscillations of two-component Fermi gas that is kept on the repulsive branch of its energy spectrum. Not only is a paramagnetic phase explored, but also a ferromagnetically separated one. Both in-, and out-of-phase perturbations are investigated, showing contributions from various gas excitations. Additionally, we compare results coming from both time-dependent Hartree-Fock and density-functional approaches.
