Graph Diffusion-Advection Operator for Directed Graph Signal Processing
CHM. Chan, A. Cionca, V. Škultéty +1
Graph signal processing (GSP) provides a framework for analyzing data on irregular domains, with applications in neuroscience, finance, chemistry, and social sciences. Classical GS…
Unconventional topological edge states in one-dimensional gapless systems stemming from nonisolated hypersurface singularities
Hongwei Jia, Jing Hu, Ruo-Yang Zhang +7
Topologically protected edge states have been extensively studied in systems characterized by the topological invariants in band gaps (also called line gaps). In this study, we unv…
Bulk-spatiotemporal vortex correspondence in gyromagnetic double-zero-index media
Ruo-Yang Zhang, Xiaohan Cui, Yuan-Song Zeng +8
Photonic double-zero-index media, distinguished by concurrently zero-valued permittivity and permeability, exhibit extraordinary properties not found in nature. Remarkably, the not…
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…
Closed-form expressions for effective constitutive parameters and electro/magneto-strictive tensors for bi-anisotropic metamaterials and their use in optical force density calculations
Neng Wang, Shubo Wang, Zhao-Qing Zhang +1
Using a multiple scattering technique, we derived closed-form expressions for effective constitutive parameters and electro/magneto-strictive tensor components for 2D bi-anisotropi…
