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 …

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 …

Proposal for observing yang-lee criticality in rydberg atomic arrays

R Shen, T Chen, MM Aliyu, F Qin, Y Zhong, H Loh… - Physical Review Letters, 2023 - APS
Yang-Lee edge singularities (YLES) are the edges of the partition function zeros of an
interacting spin model in the space of complex control parameters. They play an important …

Non-hermitian strongly interacting Dirac fermions

XJ Yu, Z Pan, L Xu, ZX Li - Physical Review Letters, 2024 - APS
Exotic quantum phases and phase transition in the strongly interacting Dirac systems have
attracted tremendous interests. On the other hand, non-Hermitian physics, usually …

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 …

Enhancement of second-order non-Hermitian skin effect by magnetic fields

CA Li, B Trauzettel, T Neupert, SB Zhang - Physical Review Letters, 2023 - APS
The non-Hermitian skin effect is a unique phenomenon in which an extensive number of
eigenstates are localized at the boundaries of a non-Hermitian system. Recent studies show …

Liouvillian skin effect in a one-dimensional open many-body quantum system with generalized boundary conditions

L Mao, X Yang, MJ Tao, H Hu, L Pan - Physical Review B, 2024 - APS
The non-Hermitian skin effect, in which eigenstates of non-Hermitian Hamiltonians are
localized at one boundary in the open boundary condition, has attracted great interest …

Enhanced many-body quantum scars from the non-Hermitian Fock skin effect

R Shen, F Qin, JY Desaules, Z Papić, CH Lee - Physical Review Letters, 2024 - APS
In contrast with extended Bloch waves, a single particle can become spatially localized due
to the so-called skin effect originating from non-Hermitian pumping. Here we show that in …

Non-Hermitian skin effect in a one-dimensional interacting Bose gas

L Mao, Y Hao, L Pan - Physical Review A, 2023 - APS
Non-Hermitian skin effect (NHSE) is a unique feature studied extensively in noninteracting
non-Hermitian systems. In this paper, we extend the NHSE originally discovered in …
