Realizing anomalous Floquet non-Abelian band topology in photonic scattering networks
Yuze Hu, Mingyu Tong, Tian Jiang +10
The concept of multi-gap topology has recently been shown to give rise to uncharted phases beyond conventional single-gap classifications. These phases relate to band nodes with no…

Photonic antiferromagnetic topological insulator with a single surface Dirac cone
Fujia Chen, Ning Han, Songyang Pu +12
Antiferromagnetism, characterized by magnetic moments aligned in alternating directions with a vanished ensemble average, has garnered renewed interest for its potential applicatio…

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…
