Sachdev-Ye-Kitaev models and beyond: Window into non-Fermi liquids

D Chowdhury, A Georges, O Parcollet… - Reviews of Modern Physics, 2022 - APS
This is a review of the Sachdev-Ye-Kitaev (SYK) model of compressible quantum many-
body systems without quasiparticle excitations, and its connections to various theoretical …

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 …

Quantum advantage in the charging process of Sachdev-Ye-Kitaev batteries

D Rossini, GM Andolina, D Rosa, M Carrega… - Physical Review Letters, 2020 - APS
The exactly solvable Sachdev-Ye-Kitaev (SYK) model has recently received considerable
attention in both condensed matter and high energy physics because it describes quantum …

Many-body chaos in the Sachdev-Ye-Kitaev model

B Kobrin, Z Yang, GD Kahanamoku-Meyer, CT Olund… - Physical review …, 2021 - APS
Many-body chaos has emerged as a powerful framework for understanding thermalization in
strongly interacting quantum systems. While recent analytic advances have sharpened our …

Lindbladian dissipation of strongly-correlated quantum matter

L Sá, P Ribeiro, T Prosen - Physical Review Research, 2022 - APS
We propose the Sachdev-Ye-Kitaev Lindbladian as a paradigmatic solvable model of
dissipative many-body quantum chaos. It describes N strongly coupled Majorana fermions …

Treelike interactions and fast scrambling with cold atoms

G Bentsen, T Hashizume, AS Buyskikh, EJ Davis… - Physical review …, 2019 - APS
We propose an experimentally realizable quantum spin model that exhibits fast scrambling,
based on nonlocal interactions that couple sites whose separation is a power of 2. By …

Minimal model for fast scrambling

R Belyansky, P Bienias, YA Kharkov, AV Gorshkov… - Physical review …, 2020 - APS
We study quantum information scrambling in spin models with both long-range all-to-all and
short-range interactions. We argue that a simple global, spatially homogeneous interaction …

Thermofield dynamics: Quantum chaos versus decoherence

Z Xu, A Chenu, T Prosen, A del Campo - Physical Review B, 2021 - APS
Quantum chaos imposes universal spectral signatures that govern the thermofield dynamics
of a many-body system in isolation. The fidelity between the initial and time-evolving …

Ultra-stable charging of fast-scrambling SYK quantum batteries

D Rosa, D Rossini, GM Andolina, M Polini… - Journal of High Energy …, 2020 - Springer
A bstract Collective behavior strongly influences the charging dynamics of quantum batteries
(QBs). Here, we study the impact of nonlocal correlations on the energy stored in a system of …
