Noncommuting conserved charges in quantum thermodynamics and beyond

S Majidy, WF Braasch Jr, A Lasek, T Upadhyaya… - Nature Reviews …, 2023 - nature.com
Thermodynamic systems typically conserve quantities (known as charges) such as energy
and particle number. The charges are often assumed implicitly to commute with each other …

Dynamics and transport at the threshold of many-body localization

S Gopalakrishnan, SA Parameswaran - Physics Reports, 2020 - Elsevier
Many-body localization (MBL) describes a class of systems that do not approach thermal
equilibrium under their intrinsic dynamics; MBL and conventional thermalizing systems form …

Semiclassical 3D gravity as an average of large-c CFTs

J Chandra, S Collier, T Hartman, A Maloney - Journal of High Energy …, 2022 - Springer
A bstract A two-dimensional CFT dual to a semiclassical theory of gravity in three
dimensions must have a large central charge c and a sparse low energy spectrum. This …

Scrambling is necessary but not sufficient for chaos

N Dowling, P Kos, K Modi - Physical Review Letters, 2023 - APS
We show that out-of-time-order correlators (OTOCs) constitute a probe for local-operator
entanglement (LOE). There is strong evidence that a volumetric growth of LOE is a faithful …

Late time correlation functions, baby universes, and ETH in JT gravity

P Saad - arXiv preprint arXiv:1910.10311, 2019 - arxiv.org
Quantum black holes are described by a large number of macroscopically indistinguishable
microstates. Correlation functions of fields outside the horizon at long time separation probe …

Random statistics of OPE coefficients and Euclidean wormholes

A Belin, J De Boer - Classical and Quantum Gravity, 2021 - iopscience.iop.org
We propose an ansatz for OPE coefficients in chaotic conformal field theories which
generalizes the eigenstate thermalization hypothesis and describes any OPE coefficient …

Bounds on chaos from the eigenstate thermalization hypothesis

C Murthy, M Srednicki - Physical review letters, 2019 - APS
We show that the known bound on the growth rate of the out-of-time-order four-point
correlator in chaotic many-body quantum systems follows directly from the general structure …

Eigenstate thermalization hypothesis and free probability

S Pappalardi, L Foini, J Kurchan - Physical Review Letters, 2022 - APS
Quantum thermalization is well understood via the eigenstate thermalization hypothesis
(ETH). The general form of ETH, describing all the relevant correlations of matrix elements …

Non-abelian eigenstate thermalization hypothesis

C Murthy, A Babakhani, F Iniguez, M Srednicki… - Physical Review Letters, 2023 - APS
The eigenstate thermalization hypothesis (ETH) explains why nonintegrable quantum many-
body systems thermalize internally if the Hamiltonian lacks symmetries. If the Hamiltonian …

Spectral statistics and many-body quantum chaos with conserved charge

AJ Friedman, A Chan, A De Luca, JT Chalker - Physical Review Letters, 2019 - APS
We investigate spectral statistics in spatially extended, chaotic many-body quantum systems
with a conserved charge. We compute the spectral form factor K (t) analytically for a minimal …
