Chirally frustrated superradiant phases in a Jaynes-Cummings trimer
Lin-Lin Jiang, Xuan Xie, Ya-Ping Ni +2
We investigate the emergence of frustrated quantum phases in a Jaynes-Cummings (JC) trimer with complex hopping amplitudes between the cavities, which represents the smallest frust…

Controlling the superradiant phase transition in the quantum Rabi model
Xuan Xie, Cheng Liu, Lin-Lin Jiang +1
In the ultrastrong-coupling regime, the quantum Rabi model can exhibit quantum phase transition (QPT) when the ratio of the qubit transition frequency to the frequency of the cavit…
