Phase diagram of a two-component Fermi gas with resonant interactions
The pairing of fermions is at the heart of superconductivity and superfluidity. The stability of these pairs determines the robustness of the superfluid state, and the quest for superconductors with high critical temperature is a search for systems with strong pairing mechanisms. Ultracold atomic Fermi gases have emerged as a highly controllable model system for studying strongly interacting fermions. Tunable interactions utilizing Feshbach collisional resonances and control of population or mass imbalance among the spin components provide unique opportunities to investigate the stability of pairing, and possibly to search for new exotic forms of superfluidity.
