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…

Experimental demonstration of non-adjacent band topology connecting multiple nodal links
Dongyang Wang, Biao Yang, Mudi Wang +5
Nodal links are special configurations of band degeneracies in the momentum space, where nodal line branches encircle each other. In PT symmetric systems, nodal lines can be topolo…

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…
