Quantum Criticality Driven by the Cavity Coupling in the Rabi-Dimer Model
The superradiant phase transition (SPT) controlled by the interacting strength between the two-level atom and the photons has been a hot topic in the Rabi model and the Rabi-dimer model. Thelatter describes two Rabi cavities coupled with an inter-cavity hopping parameter. Moreover, theSPT in the Rabi-dimer model is found to …
