Nonequilibrium dynamics and thermodynamics of a degenerate Fermi gas across a Feshbach resonance

A. V. Andreev, V. Gurarie, L. Radzihovsky

We consider a two-species degenerate Fermi gas coupled by a diatomic Feshbach resonance. We show that the resulting superfluid can exhibit a form of coherent BEC-to-BCS oscillation…
