We give a brief overview of recent studies of quantum degenerate regimes in ultracold Fermi gases. The attention is focused on the regime of Bose-Einstein condensation of weakly bound molecules of fermionic atoms, formed at a large positive scattering length for the interspecies atom-atom interaction. We analyze remarkable collisional stability of these molecules and draw prospects for future studies.

We review recent experimental studies on polarized atomic Fermi gases. The particular focus is on our own experiments of strongly interacting two-component Fermi gases with imbalanced populations. The real-space density distributions reveal a superfluid/normal phase separation at very low temperatures, accompanied by deformation of evenly paired core; at higher temperatures, a partially polarized phase is observed.
