Quantum time reflection and refraction of ultracold atoms
Zhaoli Dong, Hang Li, Tuo Wan +3
Time reflection and refraction are temporal analogies of the spatial boundary effects derived from Fermat's principle. They occur when classical waves strike a time boundary where…

Photonic Floquet skin-topological effect
Yeyang Sun, Xiangrui Hou, Tuo Wan +4
Non-Hermitian skin effect and photonic topological edge states are of great interest in non-Hermitian physics and optics. However, the interplay between them is largly unexplored.…

Observation of dynamical degeneracy splitting for the non-Hermitian skin effect
Tuo Wan, Kai Zhang, Junkai Li +2
The non-Hermitian skin effect is a distinctive phenomenon in non-Hermitian systems, which manifests as the anomalous localization of bulk states at the boundary. To understand the…
