Abstract

Superfluid-insulator transition in an ultracold Fermi gas in the external disorder potential of the amplitude $V_0$ is studied as a function of the concentration of the gas $n$ and magnetic field $B$ in the presence of the Feshbach resonance. We find the zero temperature phase diagrams in the plane ( $B,n$ ) at a given $V_0$ and in the plane $(V_0, n)$ at a given $B$ . Our results for BEC side of the diagram are also valid for the superfluid-insulator transition in a Bose gas.
