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 …

Anti-parity-time symmetry in a Su-Schrieffer-Heeger sonic lattice

B Hu, Z Zhang, Z Yue, D Liao, Y Liu, H Zhang… - Physical Review Letters, 2023 - APS
The Su-Schrieffer-Heeger (SSH) model is an important cornerstone in modern condensed-
matter topology, yet it is the simplest one-dimensional (1D) tight binding approach to dwell …

Non-hermitian mott skin effect

T Yoshida, SB Zhang, T Neupert, N Kawakami - Physical Review Letters, 2024 - APS
We propose a novel type of skin effects in non-Hermitian quantum many-body systems that
we dub a “non-Hermitian Mott skin effect.” This phenomenon is induced by the interplay …

Singular-value statistics of non-Hermitian random matrices and open quantum systems

K Kawabata, Z **ao, T Ohtsuki, R Shindou - PRX Quantum, 2023 - APS
The spectral statistics of non-Hermitian random matrices are of importance as a diagnostic
tool for chaotic behavior in open quantum systems. Here, we investigate the statistical …

Non-Hermitian photonic band winding and skin effects: a tutorial

H Wang, J Zhong, S Fan - Advances in Optics and Photonics, 2024 - opg.optica.org
Non-Hermitian band structures have gained considerable attention due to the novel

Non-Hermitian Fermi-Dirac distribution in persistent current transport

PX Shen, Z Lu, JL Lado, M Trif - Physical Review Letters, 2024 - APS
Persistent currents circulate continuously without requiring external power sources. Here,
we extend their theory to include dissipation within the framework of non-Hermitian quantum …

Many-body non-hermitian skin effect for multipoles

J Gliozzi, G De Tomasi, TL Hughes - Physical review letters, 2024 - APS
In this Letter, we investigate the fate of the non-Hermitian skin effect in one-dimensional
systems that conserve the dipole moment and higher moments of an associated global U (1) …
