    Abstract

    It is shown by microscopic calculations for trapped imbalanced Fermi superfluids that the gap function always has sign changes, i.e., the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO)-like state, up to a critical imbalance Pc, beyond which normal state becomes stable, at temperature T=0. A temperature-versus-pressure phase diagram is constructed, where the BCS state without sign change is stable only at T 0. We reproduce the observed bimodality in the density profile to identify its origin and evaluate Pc as functions of T and the coupling strength. These dependencies match with the recent experiments.
