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…
Three-dimensional non-reciprocal transport in photonic topological heterostructure of arbitrary shape
Mudi Wang, Ruo-Yang Zhang, Chenyu Zhang +6
Electromagnetic wave propagation in three-dimensional space typically suffers omnidirectional scattering when encountering obstacles. In this study, we employed Chern vectors to co…
Gauge Field Induced Chiral Zero Mode in Five-dimensional Yang Monopole Metamaterials
Shaojie Ma, Hongwei Jia, Yangang Bi +5
Owing to the chirality of Weyl nodes characterized by the first Chern number, a Weyl system supports one-way chiral zero modes under a magnetic field, which underlies the celebrate…
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 realization of chiral Landau levels in two-dimensional Dirac cone systems with inhomogeneous effective mass
Hongwei Jia, Mudi Wang, Shaojie Ma +3
Chiral zeroth Landau levels are topologically protected bulk states that give rise to chiral anomaly. Previous discussions on such chiral Landau levels are based on three-dimension…
Topological classification for intersection singularities of exceptional surfaces in pseudo-Hermitian systems
Hongwei Jia, Ruo-Yang Zhang, Jing Hu +3
Exceptional points play a pivotal role in the topology of non-Hermitian systems, and significant advances have been made in classifying exceptional points and exploring the associa…
Chiral transport of pseudo-spinors induced by synthetic gravitational field in photonic Weyl metamaterials
Hongwei Jia, Ruo-Yang Zhang, Wenlong Gao +2
Weyl particles exhibit chiral transport property under external curved space-time geometry. This effect is called chiral gravitational effect, which plays an important role in quan…
