Nonreciprocal subdiffraction imaging with staggered gyromagnetic photonic crystals
Rui Ding, Tianshu Zhang, Jiarui Yu +4
Subdiffraction imaging serves as a novel technique to enhance the optical imaging resolution, where a backscattering-free approach remains so far unavailable. Here, we theoreticall…

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…

Unconventional topological edge states in one-dimensional gapless systems stemming from nonisolated hypersurface singularities
Hongwei Jia, Jing Hu, Ruo-Yang Zhang +7
Topologically protected edge states have been extensively studied in systems characterized by the topological invariants in band gaps (also called line gaps). In this study, we unv…
