Figure 1: T–p phase diagram of a homogeneous 6Li–40K mixture at unitarity.

Figure 1

Here “PG” and “PS” indicate pseudogapped normal state and phase separation, respectively, and LP labels a Lifshitz point. An FFLO superfluid (gray shaded) phase exists in the high p regime when 40K dominates, while it becomes unstable in the dotted region. A Sarma superfluid lives in the intermediate T and low p regime (brown shaded region).
