[HTML][HTML] Topological non-Hermitian skin effect

R Lin, T Tai, L Li, CH Lee - Frontiers of Physics, 2023 - Springer
This article reviews recent developments in the non-Hermitian skin effect (NHSE),
particularly on its rich interplay with topology. The review starts off with a pedagogical …

A review on non-Hermitian skin effect

X Zhang, T Zhang, MH Lu, YF Chen - Advances in Physics: X, 2022 - Taylor & Francis
The past decades have witnessed the flourishing of non-Hermitian physics in non-
conservative systems, leading to unprecedented phenomena of unidirectional invisibility …

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 …

Non-Hermitian skin effect and self-acceleration

S Longhi - Physical Review B, 2022 - APS
Non-Hermitian systems exhibit nontrivial band topology and a strong sensitivity of the
energy spectrum on the boundary conditions. Remarkably, a macroscopic number of bulk …

Dynamical degeneracy splitting and directional invisibility in non-Hermitian systems

K Zhang, C Fang, Z Yang - Physical Review Letters, 2023 - APS
In this Letter, we introduce the concept of dynamical degeneracy splitting to describe the
anisotropic decay behaviors in non-Hermitian systems. We demonstrate that systems with …

Emergent entanglement phase transitions in non-Hermitian Aubry-André-Harper chains

SZ Li, XJ Yu, Z Li - Physical Review B, 2024 - APS
We investigate the entanglement dynamics of the non-Hermitian Aubry-André-Harper chain.
The results reveal that by increasing quasiperiodic strength, a phase transition occurs from …

Universal competitive spectral scaling from the critical non-Hermitian skin effect

F Qin, Y Ma, R Shen, CH Lee - Physical Review B, 2023 - APS
Recently, it was discovered that certain non-Hermitian systems can exhibit qualitative
different properties at different system sizes, such as being gapless at small sizes and …

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 …

Nonequilibrium dynamics of the localization-delocalization transition in the non-Hermitian Aubry-André model

LJ Zhai, GY Huang, S Yin - Physical Review B, 2022 - APS
In this paper, we investigate the driven dynamics of the localization transition in the non-
Hermitian Aubry-André model with the periodic boundary condition. Depending on the …
