Realization and Topological Properties of Third-Order Exceptional Lines Embedded in Exceptional Surfaces
Weiyuan Tang, Kun Ding, Guancong Ma
As the counterpart of Hermitian nodal structures, the geometry formed by exceptional points (EPs), such as exceptional lines (ELs), entails intriguing spectral topology. We report…

Non-Hermitian eigenvalue knots and their isotopic equivalence
Zhen Li, Kun Ding, Guancong Ma
The spectrum of a non-Hermitian system generically forms a two-dimensional complex Riemannian manifold with distinct topology from the underlying parameter space. Spectral topology…

Non-Hermitian Topology and Exceptional-Point Geometries
Kun Ding, Chen Fang, Guancong Ma
Non-Hermitian theory is a theoretical framework that excels at describing open systems. It offers a powerful tool in the characterization of both the intrinsic degrees of freedom (…
