Phase diagram of ultracold Fermi gases with tunable attractive interaction.

Caption

The vertical axis is the temperature divided by the Fermi temperature, and the horizontal axis is the attractive interaction strength. The red solid curve shows the superfluid critical temperature. The blue dashed line shows characteristic temperatures between normal and pseudogap phases. The green dotted line shows the characteristic temperatures between pseudogap and bound dimer phases. (b) Schematics for the tunneling transport process in the normal phase, the pseudogap phase, and the bound dimer phases. The Fano factor, the ratio between the current noise and the current, helps us distinguish pair-current and single-particle current.
