Superradiant Mott Transition.

Yu Chen

The combination of strongly correlated system and emergent lattice have been achieved when quantum gases are confined in a superradiant Fabry-Perot cavity. Besides the discoveries of exotic phases like density wave ordered Mott insulator and superfluid, a surprising superradiance kink is discovered experimentally. However, the proper explanation is still lacking. In this Letter, we find these kinks are the manifestation for a liquid-gas like transition between two superfluids with different densities. These kinks become divergent at the liquid-gas critical points and display a critical scaling law with a critical exponent 1 in the quantum critical region. Our predictions could be testified in current experimental setup.
