Out-of-time-order correlators and quantum chaos

I García-Mata, RA Jalabert, DA Wisniacki - arXiv preprint arXiv:2209.07965, 2022 - arxiv.org
Quantum Chaos has originally emerged as the field which studies how the properties of
classical chaotic systems arise in their quantum counterparts. The growing interest in …

From dual-unitary to quantum Bernoulli circuits: Role of the entangling power in constructing a quantum ergodic hierarchy

S Aravinda, SA Rather, A Lakshminarayan - Physical Review Research, 2021 - APS
Deterministic classical dynamical systems have an ergodic hierarchy, from ergodic through
mixing, to Bernoulli systems that are “as random as a coin toss.” Dual-unitary circuits have …

Quantum chaos without false positives

DA Trunin - Physical Review D, 2023 - APS
Out-of-time-order correlators are widely used as an indicator of quantum chaos but give
false-positive quantum Lyapunov exponents for integrable systems with isolated saddle …

Multifractal dimensions for random matrices, chaotic quantum maps, and many-body systems

A Bäcker, M Haque, IM Khaymovich - Physical Review E, 2019 - APS
Multifractal dimensions allow for characterizing the localization properties of states in
complex quantum systems. For ergodic states the finite-size versions of fractal dimensions …

Refined quantum Lyapunov exponents from replica out-of-time-order correlators

DA Trunin - Physical Review D, 2023 - APS
We suggest a new indicator of quantum chaos based on the logarithmic out-of-time-order
correlator. On the one hand, this indicator correctly reproduces the average classical …

Classical drift in the Arnold web induces quantum delocalization transition

JR Schmidt, A Bäcker, R Ketzmerick - Physical Review Letters, 2023 - APS
We demonstrate that quantum dynamical localization in the Arnold web of higher-
dimensional Hamiltonian systems is destroyed by an intrinsic classical drift. Thus quantum …

A digital image confidentiality scheme based on pseudo-quantum chaos and lucas sequence

KK Butt, G Li, F Masood, S Khan - Entropy, 2020 - mdpi.com
Several secure image encryption systems have been researched and formed by chaotic
mechanisms in current decades. This work recommends an innovative quantum color image …

Universal spectral correlations in interacting chaotic few-body quantum systems

F Fritzsch, MFI Kieler - Physical Review E, 2024 - APS
The emergence of random matrix spectral correlations in interacting quantum systems is a
defining feature of quantum chaos. We study such correlations in terms of the spectral form …

[图书][B] Dynamics, information and complexity in quantum systems

F Benatti - 2009 - Springer
Focus of the first edition of this book was quantum dynamics in connection with correlations
as carriers of information and entropy as a measure of information. In the same spirit, this …

Spectral problems in open quantum chaos

S Nonnenmacher - Nonlinearity, 2011 - iopscience.iop.org
We present an overview of mathematical results and methods relevant for the spectral study
of semiclassical Schrödinger (or wave) operators of scattering systems, in cases where the …
