Topology of Photonic Time Crystals under Complex Refractive Index Modulation
Huili Lin, Zhaohui Dong, Xianfeng Chen +1
Photonic time crystals, constructed by periodic modulation of electromagnetic parameters in time, hold unique topological properties. Here, we explore permittivity and conductivity…

Dissipative dynamics and superradiant countinuous time crystal in a Rydberg-dressed Dicke system
Haohang Zhou, Xianfeng Chen, Luqi Yuan
The interplay between many-body interactions and controlled dissipation provides a rich framework for exploring nonequilibrium quantum phases. In this work, we explore an open Dick…
