Time-Reversal Invariant Topological Photonic Alloy
Feng Ruili, Qu Tiantao, Wu Xianbin +4
Conventional approaches generate quantum spin Hall (QSH) and quantum valley Hall (QVH) effects by breaking spatial inversion symmetry across the entire photonic crystal. Consequent…

Fragility of Unidirectional Transport in Weakly Disordered Photonic Chern Insulators
Xiaoxuan Shi, Tiantao Qu, Xianbin Wu +3
Photonic Chern insulators enable unidirectional light transport protected by nontrivial band topology -- essential for robust photonic integrated circuits and error-free communicat…
