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 …

Observation of the non-Hermitian skin effect and Fermi skin on a digital quantum computer

R Shen, T Chen, B Yang, CH Lee - Nature Communications, 2025 - nature.com
Lately, the non-Hermitian skin effect (NHSE) has been demonstrated in various classical
metamaterials and even ultracold atomic arrays. Yet, its interplay with many-body dynamics …

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 pum**. Here we show that in …

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 …

Realization of higher-order topological lattices on a quantum computer

JM Koh, T Tai, CH Lee - Nature Communications, 2024 - nature.com
Programmable quantum simulators may one day outperform classical computers at certain
tasks. But at present, the range of viable applications with noisy intermediate-scale quantum …

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 …

Observation of non-Hermitian edge burst in quantum dynamics

L **ao, WT Xue, F Song, YM Hu, W Yi, Z Wang… - Physical Review Letters, 2024 - APS
The non-Hermitian skin effect, by which the eigenstates of the Hamiltonian are
predominantly localized at the boundary, has revealed a strong sensitivity of non-Hermitian …

Zoology of non-Hermitian spectra and their graph topology

T Tai, CH Lee - Physical Review B, 2023 - APS
We uncover the very rich graph topology of generic bounded non-Hermitian spectra, distinct
from the topology of conventional band invariants and complex spectral winding. The graph …

Percolation-Induced Symmetry Breaking

M Yang, CH Lee - Physical Review Letters, 2024 - APS
We propose a new avenue in which percolation, which has been much associated with
critical phase transitions, can also dictate the asymptotic dynamics of non-Hermitian systems …

Impedance responses and size-dependent resonances in topolectrical circuits via the method of images

H Sahin, ZB Siu, SM Rafi-Ul-Islam, JF Kong, MBA Jalil… - Physical Review B, 2023 - APS
Resonances in an electric circuit occur when capacitive and inductive components are
present together. Such resonances appear in admittance measurements depending on the …
