Lessons from the information paradox

S Raju - Physics Reports, 2022 - Elsevier
We review recent progress on the information paradox. We explain why exponentially small
correlations in the radiation emitted by a black hole are sufficient to resolve the original …

Emergent times in holographic duality

S Leutheusser, H Liu - Physical Review D, 2023 - APS
In holographic duality an eternal Anti-de Sitter black hole is described by two copies of the
boundary Conformal Field Theory in the thermal field double state. In this paper we provide …

Islands outside the horizon

A Almheiri, R Mahajan, J Maldacena - arXiv preprint arXiv:1910.11077, 2019 - arxiv.org
We consider an AdS $ _2 $ black hole in equilibrium with a bath, which we take to have a
dual description as (0+ 1)-dimensional quantum mechanical system coupled to a (1+ 1) …

Black holes and random matrices

JS Cotler, G Gur-Ari, M Hanada, J Polchinski… - Journal of High Energy …, 2017 - Springer
A bstract We argue that the late time behavior of horizon fluctuations in large anti-de Sitter
(AdS) black holes is governed by the random matrix dynamics characteristic of quantum …

Entanglement islands in higher dimensions

A Almheiri, R Mahajan, J Santos - SciPost Physics, 2020 - scipost.org
It has been suggested in recent work that the Page curve of Hawking radiation can be
recovered using computations in semi-classical gravity provided one allows for" islands" in …

A semiclassical ramp in SYK and in gravity

P Saad, SH Shenker, D Stanford - arXiv preprint arXiv:1806.06840, 2018 - arxiv.org
In finite entropy systems, real-time partition functions do not decay to zero at late time.
Instead, assuming random matrix universality, suitable averages exhibit a growing" ramp" …

Microscopic origin of the entropy of black holes in general relativity

V Balasubramanian, A Lawrence, JM Magán… - Physical Review X, 2024 - APS
We construct an infinite family of microstates with geometric interiors for eternal black holes
in general relativity with a negative cosmological constant in any dimension. Wormholes in …

The factorization problem in Jackiw-Teitelboim gravity

D Harlow, D Jafferis - Journal of High Energy Physics, 2020 - Springer
A bstract In this note we study the 1+ 1 dimensional Jackiw-Teitelboim gravity in Lorentzian
signature, explicitly constructing the gauge-invariant classical phase space and the quantum …

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 …

Failure of the split property in gravity and the information paradox

S Raju - Classical and Quantum Gravity, 2022 - iopscience.iop.org
In an ordinary quantum field theory, the'split property'implies that the state of the system can
be specified independently on a bounded subregion of a Cauchy slice and its complement …
