Self-healing of non-Hermitian topological skin modes
S Longhi - Physical Review Letters, 2022 - APS
A unique feature of non-Hermitian (NH) systems is the NH skin effect, ie, the edge
localization of an extensive number of bulk-band eigenstates in a lattice with open or semi …

Dimensional transmutation from non-hermiticity
H Jiang, CH Lee - Physical Review Letters, 2023 - APS
Dimensionality plays a fundamental role in the classification of novel phases and their
responses. In generic lattices of 2D and beyond, however, we found that non-Hermitian …

Dynamical degeneracy splitting and directional invisibility in non-Hermitian systems
In this Letter, we introduce the concept of dynamical degeneracy splitting to describe the

Anomalous skin effects in disordered systems with a single non-Hermitian impurity
P Molignini, O Arandes, EJ Bergholtz - Physical Review Research, 2023 - APS
We explore anomalous skin effects at non-Hermitian impurities by studying their interplay
with potential disorder and by exactly solving a minimal lattice model. A striking feature of …
