Twin reflections from a moving space-time boundary
Yukun Yang, Hao Hu, Youxiu Yu +7
The authors experimentally demonstrate that a moving space‑time boundary (an interluminal interface) splits an incoming wave into one transmitted and two reflected waves, confirmin…

Fundamentals and Applications of Time-varying Media: A Review
Youxiu Yu, Hao Hu, Qianru Yang +4
Time-varying media, characterized by dynamic or spacetime-modulated constitutive parameters such as permittivity and permeability, have recently emerged as a transformative paradig…

Observation of wave amplification and temporal topological state in a genuine photonic time crystal
Jiang Xiong, Xudong Zhang, Longji Duan +6
Photonic time crystals (PTCs) are materials whose dielectric permittivity is periodically modulated in time, giving rise to bandgaps not in energy-as in conventional photonic cryst…
