Non-Hermiticity of an anomalous superradiant phase
Jun-Ling Wang, You-Qi Lu, Qing-Hu Chen +1
We counterintuitively present a Hermitian squeezing-Dicke model as a minimal setting for non-Hermitian physics in many-body light-matter systems. It enables the realization of a no…
Quantum Criticality from Spectral Collapse in the Two-Photon Rabi Model
Jiong Li, Jun-Ling Wang, Jun-ling Wang +2
Spectral collapse in the two-photon quantum Rabi model (tpQRM) has long been regarded as insufficient to establish quantum criticality because, under generic conditions, the lowest…
Superradiant phase transitions in the quantum Rabi model: Overcoming the no-go theorem through anisotropy
Tian Ye, Yan-Zhi Wang, Xiang-You Chen +2
Although the superradiant phase transition (SRPT) is prohibited in the paradigmatic quantum Rabi model due to the no-go theorem caused by the term, we demonstrate tw…
Phase Transitions in the Anisotropic Dicke-Stark Model with -square terms
Xiang-You Chen, Yu-Yu Zhang, Qing-Hu Chen +1
The superradiant phase transition (SRPT) is forbidden in the standard isotropic Dicke model due to the so-called no-go theorem induced by A-square term. In the framework of the Dic…
