Description
We study theoretically the collective modes of a
two-component Fermi gas with attractive interactions in a
quasi-one-dimensional harmonic trap. We focus on an
imbalanced gas in the Fulde-Ferrell-Larkin-Ovchinnikov
(FFLO) phase. Using a mean-field theory, we study the
response of the ground state to time-dependent potentials.
For potentials with short wavelengths, we find dramatic
signatures in the large-scale response of the gas which are
characteristic of the FFLO phase. This response provides an
effective way to detect the FFLO state in experiments.
