Intrinsic triple degeneracy point bounded by nodal surfaces in chiral photonic crystal
Dongyang Wang, Hongwei Jia, Quanlong Yang +3
In periodic systems, band degeneracies are usually protected and classified by spatial symmetries. However, the Gamma point at zero-frequency of a photonic system is an intrinsic d…
Demonstration of non-Abelian frame charge flow in photonic crystals
Dongyang Wang, Z. Q. Zhang, C. T. Chan
In PT symmetric systems, the notion of non-Abelian frame charges enables multiband topological characterization of the degeneracy nodes through examining the eigenvector frame rota…
Arbitrary order exceptional point induced by photonic spin-orbit interaction in coupled resonators
Shubo Wang, Bo Hou, Weixin Lu +3
Many novel properties of non-Hermitian systems are found at or near the exceptional points-branch points of complex energy surfaces at which eigenvalues and eigenvectors coalesce.…
Synthetic gauge fields and Weyl point in Time-Reversal Invariant Acoustic Systems
Meng Xiao, Wen-Jie Chen, Wen-Yu He +2
Inspired by the discovery of quantum hall effect and topological insulator, topological properties of classical waves start to draw worldwide attention. Topological non-trivial ban…
