Mechanism for scale-free skin effect in one-dimensional systems
Shu-Xuan Wang
Non-Hermitian skin effect (NHSE) is one of the most fascinating phenomena in non-Hermitian systems, which refers to enormous eigenstates localize at the boundary exponentially unde…
Theory for the spectral splitting exponent of exceptional points
Shu-Xuan Wang, Zhongbo Yan
Exceptional points (EPs), singularities in non-Hermitian systems where eigenvalues and eigenstates coalesce, exhibit a dramatically enhanced response to perturbations compared to H…
Super-enhanced Sensitivity in Non-Hermitian Systems at Infernal Points
Shu-Xuan Wang, Zhongbo Yan
The emergence of exceptional points in non-Hermitian systems represents an intriguing phenomenon characterized by the coalescence of eigenenergies and eigenstates. When a system ap…
General theory for infernal points in non-Hermitian systems
Shu-Xuan Wang, Zhongbo Yan
The coalescence of eigenstates is a unique phenomena in non-Hermitian systems. Remarkably, it has been noticed in some non-Hermitian systems under open boundary conditions that the…
