Quantum criticality from spectral collapse in the two-photon Rabi model
Jiong Li, Jun-ling Wang, Qing-Hu Chen +1
Spectral collapse in the two-photon quantum Rabi model (tpQRM) has long been regarded as incompatible with quantum criticality due to the absence of a vanishing excitation gap. We…

Dissipative phase transitions of the Dicke-Ising model
Jun-Ling Wang, Jiong Li, Qing-Hu Chen
The dissipative phase transitions in the open transverse and longitudinal Dicke-Ising model (DIM), which incorporates nearest-neighbor Ising-type spin interactions into the Dicke f…

Emergence of Rich Dissipative Phases in the Anisotropic Quantum Rabi Model Driven by the Term
Jun-Ling Wang, Yi-bo Liu, Qing-Hu Chen
The open quantum Rabi model is studied in this work, with the explicit term incorporated. It is shown that anisotropy provides a generic and robust mechanism for e…
