Interplay between non-Hermiticity and non-Abelian gauge potential in topological photonics
Jia-Qi Cai, Qing-Yun Yang, Zheng-Yuan Xue +3
Topological phases in spinless non-Hermitian models have been widely studied both theoretically and experimentally in some artificial materials using photonics, phononics and magno…

Out-of-time-order correlators and quantum phase transitions in the Rabi and Dicke model
Zheng-Hang Sun, Jia-Qi Cai, Qi-Cheng Tang +2
The out-of-time-order correlators (OTOCs) is used to study the quantum phase transitions (QPTs) between the normal phase and the superradiant phase in the Rabi and few-body Dicke m…
