Abstract

A rotating ultracold S-wave superfluid Fermi gas is studied when the mismatch in chemical potentials \ensuremathδ\ensuremathμ (and the population imbalance \ensuremathδn) corresponds to the Larkin-Ovchinnikov-Fulde-Ferrell state in the vicinity of the Lifshitz critical point. It is shown that under these conditions the critical angular velocity \ensuremathΩ_c2 in two-dimensional systems is an oscillating function of temperature and \ensuremathδn giving rise to reentrant superfluid phases. The reason for this behavior is the population by Cooper pairs of the Landau levels (n\ensuremath≥1) above the lowest one (n=0).
