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 its concentration n and the 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. We study the transition between cases of classical and quantum random potentials which can be implemented by tuning intensity of speckles. Our results for the Bose-Einstein condensation side of the diagram are also valid for a Bose gas.
