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 …

Transport properties in non-Fermi liquid phases of nodal-point semimetals

I Mandal, H Freire - Journal of Physics: Condensed Matter, 2024 - iopscience.iop.org
In this review, we survey the current progress in computing transport properties in
semimetals which harbour non-Fermi liquid (NFL) phases. We first discuss the widely-used …

Measurement-induced phase transition in the monitored Sachdev-Ye-Kitaev model

SK Jian, C Liu, X Chen, B Swingle, P Zhang - Physical review letters, 2021 - APS
We construct Brownian Sachdev-Ye-Kitaev (SYK) chains subjected to continuous monitoring
and explore possible entanglement phase transitions therein. We analytically derive the …

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 …

Thermalization of non-Fermi-liquid electron-phonon systems: Hydrodynamic relaxation of the Yukawa-Sachdev-Ye-Kitaev model

H Hosseinabadi, SP Kelly, J Schmalian, J Marino - Physical Review B, 2023 - APS
We study thermalization dynamics in a fermion-phonon variant of the Sachdev-Ye-Kitaev
model coupled to an external cold thermal bath of harmonic oscillators. We find that …

Subsystem Rényi entropy of thermal ensembles for SYK-like models

P Zhang, C Liu, X Chen - SciPost Physics, 2020 - scipost.org
Abstract The Sachdev-Ye-Kitaev model is an $ N $-modes fermionic model with infinite
range random interactions. In this work, we study the thermal R\'enyi entropy for a subsystem …

Eigenstate capacity and Page curve in fermionic Gaussian states

B Bhattacharjee, P Nandy, T Pathak - Physical Review B, 2021 - APS
Capacity of entanglement (CoE), an information-theoretic measure of entanglement, defined
as the variance of modular Hamiltonian, is known to capture the deviation from the maximal …

Dynamical onset of light-induced unconventional superconductivity—a Yukawa-Sachdev-Ye-Kitaev study

L Grunwald, G Passetti, DM Kennes - Communications Physics, 2024 - nature.com
Using light irradiation to manipulate quantum materials has opened up avenues for
transiently inducing superconductivity in some systems. Despite experimental confirmation …

Nanowelding of quantum spin- chains at minimal dissipation

MF Cavalcante, MVS Bonança, E Miranda, S Deffner - Physical Review B, 2024 - APS
We consider the optimal control of switching on a coupling term between two quantum many-
body systems. Specifically, we (i) quantify the energetic cost of establishing a weak junction …

Floquet SYK wormholes

M Berenguer, A Dey, J Mas, J Santos-Suárez… - Journal of High Energy …, 2024 - Springer
A bstract We study the non-equilibrium dynamics of two coupled SYK models, conjectured to
be holographically dual to an eternal traversable wormhole in AdS 2. We consider different …
