Topology reconstruction for asymmetric systems by isomorphic mapping or perturbation approximation
Yunlin Li, Jingguang Chen, Xingchao Qi +6
The systems without symmetries, e.g. the spatial and chiral symmetries, are generally thought to be improper for topological study and no conventional integral topological invarian…
Scattering Singularity in Topological Dielectric Photonic Crystals
Langlang Xiong, Xunya Jiang, Guangwei Hu
The exploration of topology in natural materials and metamaterials has garnered significant attention. Notably, the one-dimensional (1D) and two-dimensional (2D) Su-Schrieffer-Heeg…
Enhancement of spin-orbit interaction and nearly perfect spin-conversion by 1D photonic crystal with the anisotropic defect layer
Xianjun Wang, Yufu Liu, Yunlin Li +2
Although photon spin-orbit interaction (SOI) has been extensively studied, the vortex-conversion efficiency and the enhancement of spin Hall effect in abnormal modes in SOI remain…
Dual-polarization huge photonic spin Hall shift and deep-subwavelength sensing based on topological singularities in one-dimensional photonic crystals
Yufu Liu, Xianjun Wang, Yunlin Li +6
Although several efforts have been taken to enhance the photonic spin Hall shift in deep-subwavelength region, according to effective medium theory, the fundamental confliction bet…
Higher-order topological states in photonic Thue-Morse quasicrystals: quadrupole insulator and a new origin of corner states
Langlang Xiong, Yu Zhang, Yufu Liu +2
Corner states (CSs) in higher-order topological insulators (HOTIs) have recently been of great interest in both crystals and quasicrystals. In contrast to electronic systems, HOTIs…
Topological properties of two-dimensional photonic square lattice without and symmetries
Langlang Xiong, Yufu Liu, Yu Zhang +2
Rich topological phenomena, edge states and two types of corner states, are unveiled in a two-dimensional square-lattice dielectric photonic crystal without both and $M_{x(y)…
