摘要：

The low energy collective mode spectrum of a superfluid Fermi gas in a spherical trap in the collisionless regime was considered. The effects of superfluidity on modes of dipole and quadrupole symmetries were systematically examined using a self-consistent random-phase approximation. For varying pairing strength and temperature, the spectrum was calculated and several features such as the emergence of Goldstone modes were identified.
