An introduction to the SYK model

V Rosenhaus - Journal of Physics A: Mathematical and …, 2019 - iopscience.iop.org
Abstract The Sachdev–Ye–Kitaev (SYK) model is a strongly coupled, quantum many-body
system that is chaotic, nearly conformally invariant, and exactly solvable. This remarkable …

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 …

Operator spreading in random unitary circuits

A Nahum, S Vijay, J Haah - Physical Review X, 2018 - APS
Random quantum circuits yield minimally structured models for chaotic quantum dynamics,
which are able to capture, for example, universal properties of entanglement growth. We …

Verified quantum information scrambling

KA Landsman, C Figgatt, T Schuster, NM Linke… - Nature, 2019 - nature.com
Quantum scrambling is the dispersal of local information into many-body quantum
entanglements and correlations distributed throughout an entire system. This concept …

Eternal traversable wormhole

J Maldacena, XL Qi - arXiv preprint arXiv:1804.00491, 2018 - arxiv.org
We construct a nearly-$ AdS_2 $ solution describing an eternal traversable wormhole. The
solution contains negative null energy generated by quantum fields under the influence of …

Quantum information scrambling in a trapped-ion quantum simulator with tunable range interactions

MK Joshi, A Elben, B Vermersch, T Brydges, C Maier… - Physical Review Letters, 2020 - APS
In ergodic many-body quantum systems, locally encoded quantum information becomes, in
the course of time evolution, inaccessible to local measurements. This concept of …

An SYK-like model without disorder

E Witten - Journal of Physics A: Mathematical and Theoretical, 2019 - iopscience.iop.org
Making use of known facts about'tensor models', it is possible to construct a quantum system
without quenched disorder that has the same large n limit for its correlation functions and …

Scrambling transition in a radiative random unitary circuit

Z Weinstein, SP Kelly, J Marino, E Altman - Physical Review Letters, 2023 - APS
We study quantum information scrambling in a random unitary circuit that exchanges qubits
with an environment at a rate p. As a result, initially localized quantum information not only …
