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)…

Two Classes of Singularities and Novel Topology in a Specially Designed Synthetic Photonic Crystals
Qiucui Li, Yu Zhang, Xunya Jiang
Zak phase and topological protected edge state are usually studied in one-dimensional(1D) photonic systems with spatial inversion symmetry(SIS). Interestingly in this work, we find…
