Reflection and Refraction at Nonlinear Temporal Boundaries in Synthetic Lattices
Chong-Xiao Chen, Zheng-Wei Zhou, Xi-Wang Luo
Temporal boundaries in time-modulated media provide a powerful route toward wave manipulation beyond conventional spatial boundaries. Here, we investigate nonlinear temporal bounda…

Squeezed superradiant lasing of a quantum many-body emitter
Da-Wu Xiao, Chong Chen, Ren-Bao Liu
In conventional lasers, the emitters are typically incoherent, radiating photons independently; in superradiant lasers, many coherent emitters radiate photons collectively, but the…
