Collective excitations of the pairing states in multi-component dipolar Fermi gases

ORAL

Abstract

The multi-component ultra-cold dipolar Fermi gases exhibit competing singlet and triplet Cooper pairings. We investigate collective excitations in such states, including the gapless phonon and spin-wave Goldstone modes with anisotropic dispersions due to the anisotropic nature of the dipolar interaction. An excitonic mode in the p-wave triplet channel is predicted as a low energy resonance mode between the singlet and triplet pairing states.
