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…
