Amorphous photonic topological insulator

12 Jan 2020 Zhou Peiheng Liu Gui-Geng Ren Xin Yang Yihao Xue Haoran Bi Lei Deng Longjiang Chong Yidong Zhang Baile

Photonic topological insulators (PTIs) exhibit robust photonic edge states protected by band topology, similar to electronic edge states in topological band insulators. Standard band theory does not apply to amorphous phases of matter, which are formed by non-crystalline lattices with no long-range positional order but only short-range order... (read more)
