Frustrated Superradiant Phase Transition

Jinchen Zhao, Myung-Joong Hwang

Frustration is an interesting phenomenon in spin physics, where the system cannot minimize its energy due to conflicting constraints. We show that the order parameters during a superradiant phase transition can also be frustrated. This can lead to many exotic critical behaviors, such as the emergence of two diverging time scales.

Anomalous criticality with bounded fluctuations and long-range frustration induced by broken time-reversal symmetry

Jinchen Zhao, Myung-Joong Hwang

We identify an anomalous superradiant phase transition in the synthetic magnetic field. Due to the breaking of the time-reversal symmetry, the system can exhibit a series of first-order transitions when we tune the magnetic flux. Moreover, the system has novel behaviors in the normal phase, such as a bounded photon number, in contrast to the divergent photon number in other superradiant phase transitions.
