Spatiotemporal Co-reflection with Spacetime Discontinuities at Moving Interfaces
Yongge Wang, Jingfeng Yao, Chengxun Yuan +1
The control of reflection and refraction at interfaces using engineered media is central to numerous optical technologies, with negative refraction and the suppression of backscatt…

Breaking the Limitations of Temporal Modulation via Mixed Continuity Conditions
Yongge Wang, Jingfeng Yao, Ying Wang +2
The conventional description of time-varying media assumes that electromagnetic fields evolve according to fixed continuity conditions during parameter jumps. Here we reveal that t…

Topological Braiding and Dynamic Probing of Phase Transitions at Temporal Interfaces in Non-Hermitian Synthetic Dimensions
Yuanhang Jiang, Jianfei Li, Chengxi Yang +6
Non-Hermitian systems give rise to distinct topological phenomena, yet their manifestations at temporal interfaces characterized by abrupt changes in system parameters remain large…
