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 photonics and topological photonic states have opened up a new frontier for
optical manipulation and robust light trapping. The topological rainbow can separate …

Dynamic topological photonics is a novel research field, combining the time-domain optics
and topological physics. In this review, the recent progress and realization platforms of …

We investigate the existence of higher order topological localized modes in moiré lattices of
bilayer elastic plates. Each plate has a hexagonal array of discrete resonators and one of …

The exploration of topology in natural materials and metamaterials has garnered significant
attention. Notably, the one-dimensional (1D) and two-dimensional (2D) Su-Schrieffer …

Second‐order topological insulators can be characterized by their bulk polarization, which is
believed to be intrinsically connected to the center of the Wannier function. In this study, the …

Topological photonic crystals (PCs) can support topologically protected states of light. These
states are immune to backscattering and can be used to construct a variety of optical …

The topological photonics plays an important role in the fields of fundamental physics and
photonic devices. The traditional method of designing topological system is based on the …

We report the edge states and non-zero boundary charges in one-dimensional photonic
crystals (1D PhCs) without inversion symmetry. In contrast to common 1D systems, we show …

Higher-order topological insulators (HOTIs) is an exciting topic. We constructed a square
lattice dipole arrays, it supports out-of-plane and in-plane modes by going beyond …
