Non-Hermitian topological phenomena: A review

N Okuma, M Sato - Annual Review of Condensed Matter Physics, 2023 - annualreviews.org
The past decades have witnessed an explosion of interest in topological materials, and a lot
of mathematical concepts have been introduced in condensed matter physics. Among them …

Variational quantum simulation of lindblad dynamics via quantum state diffusion

J Luo, K Lin, X Gao - The Journal of Physical Chemistry Letters, 2024 - ACS Publications
Quantum simulation of dynamics in open quantum systems is crucial but poses a significant
challenge due to the non-Hermitian nature leading to nonunitary evolution and the limited …

Quantum-squeezing-induced point-gap topology and skin effect

LL Wan, XY Lü - Physical Review Letters, 2023 - APS
We theoretically predict the squeezing-induced point-gap topology together with a symmetry-
protected Z 2 “skin effect” in a one-dimensional (1D) quadratic-bosonic system. Protected by …

Amplification of quantum signals by the non-Hermitian skin effect

Q Wang, C Zhu, Y Wang, B Zhang, YD Chong - Physical Review B, 2022 - APS
The non-Hermitian skin effect (NHSE) is a phenomenon whereby certain non-Hermitian
lattice Hamiltonians host an extensive number of eigenmodes condensed to the boundary …

Non-Hermitian topological excitation transmission in the dimerized lattice with imaginary potential and nonreciprocal hop**

L Qi, QN Li, N Han, M Li, XY Zhang, AL He - Physical Review A, 2024 - APS
We investigate the topological edge transmission of excitation based on the one-
dimensional Su-Schrieffer-Heeger lattice with purely imaginary on-site potential and …

Topological directed amplification

B Midya - Physical Review A, 2022 - APS
A phenomenon of topological directed amplification of certain initial perturbations is
revealed theoretically to emerge in a class of asymptotically stable skin-effect lattices …
