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 …

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 …

Jackiw-Teitelboim gravity and rotating black holes

U Moitra, SK Sake, SP Trivedi, V Vishal - Journal of High Energy Physics, 2019 - Springer
A bstract We show that the free energy at low temperatures for near-extremal black holes is
correctly obtained from the Jackiw-Teitelboim (JT) model of gravity. Our arguments apply to …

Sailing past the End of the World and discovering the Island

T Anous, M Meineri, P Pelliconi, J Sonner - SciPost Physics, 2022 - scipost.org
Large black holes in anti-de Sitter space have positive specific heat and do not evaporate. In
order to mimic the behavior of evaporating black holes, one may couple the system to an …

Jackiw-Teitelboim gravity in the second order formalism

U Moitra, SK Sake, SP Trivedi - Journal of High Energy Physics, 2021 - Springer
A bstract We formulate the path integral for Jackiw-Teitelboim gravity in the second order
formalism working directly with the metric and the dilaton. We consider the theory both in …

The cosmological OTOC: A new proposal for quantifying auto-correlated random non-chaotic primordial fluctuations

S Choudhury - Symmetry, 2021 - mdpi.com
The underlying physical concept of computing out-of-time-ordered correlation (OTOC) is a
significant new tool within the framework of quantum field theory, which now-a-days is …

Phase transition and chaos in charged SYK model

N Sorokhaibam - Journal of High Energy Physics, 2020 - Springer
A bstract We study chaotic-integrable transition and the nature of quantum chaos in SYK
model with chemical potential. We use a novel numerical technique to calculate the partition …

Jackiw-Teitelboim model coupled to conformal matter in the semi-classical limit

U Moitra, SK Sake, SP Trivedi, V Vishal - Journal of High Energy Physics, 2020 - Springer
A bstract We analyse the Jackiw-Teitelboim model of 2D gravity coupled to N massless free
scalar fields in the semi-classical limit. Two systems are studied which essentially differ in …

Rotating black holes in AdS spacetime, extremality, and chaos

A Banerjee, A Kundu, RR Poojary - Physical Review D, 2020 - APS
Extremal black holes have vanishing Hawking temperatures. In this paper, we argue that for
asymptotically anti–de Sitter (AdS) black holes, at extremality, a particular class of …

Extended eigenstate thermalization and the role of FZZT branes in the Schwarzian theory

P Nayak, J Sonner, M Vielma - Journal of High Energy Physics, 2020 - Springer
A bstract In this paper we provide a universal description of the behavior of the basic
operators of the Schwarzian theory in pure states. When the pure states are energy …
