Multiresonant Membrane Metasurfaces for Multifunctional Fingerprint Recognition and Real-time Biochemical Tracking
Quanlong Yang, Yapeng Dou, Dongyang Wang +9
Label-free identification and real-time tracking of biochemical substances became critical for molecular diagnostics and chemical analysis, yet conventional resonant terahertz meta…
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…
Experimental observation of non-Abelian earring nodal links in phononic crystals
Mudi Wang, Shan Liu, Qiyun Ma +7
Nodal lines are symmetry-protected one-dimensional band degeneracies in momentum space, which can appear in numerous topological configurations such as nodal rings, chains, links,…
Photonic nodal lines with quadrupole Berry curvature distribution
Dongyang Wang, Biao Yang, Ruo-Yang Zhang +4
In periodic systems, nodal lines are loops in the three-dimensional momentum space where two bands are degenerate with each other. Nodal lines exhibit rich topological features as…
