Geometry-induced Exceptional Point Detached from Fermi Arcs
Yuancheng Zhao, Jia-Xin Zhong, Jing Lin +2
Exceptional points (EPs), ubiquitous non-Hermitian degeneracies, are central features in band structures where non-Hermitian Fermi arcs connect EPs and eigenvalue knots encircle th…
Unveiling non-Hermitian band structures with non-Bloch supercells
Jia-Xin Zhong, Jing Lin, Kai Chen +3
Real-valued band structures are foundational to analyzing periodic systems within the Hermitian description and have been experimentally well-established over recent decades. In co…
Algebraic skin effect in two-dimensional non-Hermitian metamaterials
Mingyang Li, Jing Lin, Kun Ding
Metamaterials have unlocked unprecedented control over light by leveraging novel mechanisms to expand their functionality. Non-Hermitian physics further enhances the tunability of…
Unveiling Non-Hermitian Spectral Topology in Hyperbolic Lattices with Non-Abelian Translation Symmetry
Mengying Hu, Jing Lin, Kun Ding
The hyperbolic lattice (HBL) has emerged as a compelling platform for exploring matter in non-Euclidean space. Among its notable features, the breakdown of the conventional Bloch t…
