Self-healing topological streams in space-time
Yudong Ren, Wenhao Li, Yuang Pan +2
Topological states are renowned for their robustness against perturbations. Recent advances have further introduced momentum-gap (or time) topology in time-varying media, enabling…
Three-dimensional topological valley photonics
Wenhao Li, Qiaolu Chen, Ning Han +8
Topological valley photonics, which exploits valley degree of freedom to manipulate electromagnetic waves, offers a practical and effective pathway for various classical and quantu…
Observation of temporal topological boundary states of light in a momentum bandgap
Yudong Ren, Kangpeng Ye, Qiaolu Chen +8
Topological phases have prevailed across diverse disciplines, spanning electronics, photonics, and acoustics. Hitherto, the understanding of these phases has centred on energy (fre…
Boundary-induced topological chiral extended states in Weyl metamaterial waveguides
Ning Han, Fujia Chen, Mingzhu Li +9
In topological physics, it is commonly understood that the existence of the boundary states of a topological system is inherently dictated by its bulk. A classic example is that th…
