Symmetry classification and universality in non-Hermitian many-body quantum chaos by the Sachdev-Ye-Kitaev model

AM García-García, L Sá, JJM Verbaarschot - Physical Review X, 2022 - APS
Spectral correlations are a powerful tool to study the dynamics of quantum many-body
systems. For Hermitian Hamiltonians, quantum chaotic motion is related to random matrix …

Spectral statistics of non-hermitian matrices and dissipative quantum chaos

J Li, T Prosen, A Chan - Physical review letters, 2021 - APS
We propose a measure, which we call the dissipative spectral form factor (DSFF), to
characterize the spectral statistics of non-Hermitian (and nonunitary) matrices. We show that …

Non-Hermitian many-body localization with open boundaries

K Suthar, YC Wang, YP Huang, HH Jen, JS You - Physical Review B, 2022 - APS
The explorations of non-Hermiticity have been devoted to investigate the disorder-induced
many-body localization (MBL). However, the sensitivity of the spatial boundary conditions …

Complex networks with complex weights

L Böttcher, MA Porter - Physical Review E, 2024 - APS
In many studies, it is common to use binary (ie, unweighted) edges to examine networks of
entities that are either adjacent or not adjacent. Researchers have generalized such binary …

Progress on the Study of the Ginibre Ensembles

SS Byun, PJ Forrester - 2025 - library.oapen.org
This open access book focuses on the Ginibre ensembles that are non-Hermitian random
matrices proposed by Ginibre in 1965. Since that time, they have enjoyed prominence within …

From ergodicity to many-body localization in a one-dimensional interacting non-Hermitian Stark system

J Liu, Z Xu - Physical Review B, 2023 - APS
Recent studies on disorder-induced many-body localization (MBL) in non-Hermitian
quantum systems have attracted great interest. However, the non-Hermitian disorder-free …

Singular-value statistics of directed random graphs

JA Méndez-Bermúdez, R Aguilar-Sánchez - Physical Review E, 2024 - APS
Singular-value statistics (SVS) has been recently presented as a random matrix theory tool
able to properly characterize non-Hermitian random matrix ensembles [PRX Quantum 4 …

Non-Hermitian diluted banded random matrices: Scaling of eigenfunction and spectral properties

M Hernández-Sánchez, G Tapia-Labra… - Physical Review E, 2024 - APS
Here we introduce the non-Hermitian diluted banded random matrix (nHdBRM) ensemble
as the set of N× N real nonsymmetric matrices whose entries are independent Gaussian …

Localization and universality of eigenvectors in directed random graphs

FL Metz, I Neri - Physical Review Letters, 2021 - APS
Although the spectral properties of random graphs have been a long-standing focus of
network theory, the properties of right eigenvectors of directed graphs have so far eluded an …

From integrability to chaos in quantum Liouvillians

A Rubio-García, R Molina, J Dukelsky - SciPost Physics Core, 2022 - scipost.org
The dynamics of open quantum systems can be described by a Liouvillian, which in the
Markovian approximation fulfills the Lindblad master equation. We present a family of …
