An outsider’s perspective on information recovery in de Sitter space
Journal of High Energy Physics, 2023 Entanglement islands play a crucial role in our understanding of how Hawking radiation encodes information in a black hole, but their relevance in cosmological spacetimes is less clear. In this paper, we continue our investigation of information recovery

Universal flow equations and chaos bound saturation in 2d dilaton gravity [PDF]
Journal of High Energy Physics, 2020 We show that several features of the Jackiw-Teitelboim model are in fact universal properties of two-dimensional Maxwell-dilaton gravity theories with a broad class of asymptotics.

Mabuchi spectrum from the minisuperspace
Physics Letters B, 2016 It was recently shown that other functionals contribute to the effective action for the Liouville field when considering massive matter coupled to two-dimensional gravity in the conformal gauge.

Bra-ket wormholes in gravitationally prepared states
Journal of High Energy Physics, 2021 We consider two dimensional CFT states that are produced by a gravitational path integral. As a first case, we consider a state produced by Euclidean AdS2 evolution followed by flat space evolution.

Jackiw-Teitelboim gravity and the models of a Hawking-Page transition for 2D black holes [PDF]
, 2020 We propose a top down construction for Jackiw-Teitelboim (JT) gravity using compactification of $ D=5 $ gravity theories in the presence of Abelian ($ U(1) $) as well as $ SU(2) $ Yang-Mills (YM) fields.

A c=1 phase transition in two-dimensional CDT/Horava–Lifshitz gravity?
Physics Letters B, 2015 We study matter with central charge c>1 coupled to two-dimensional (2d) quantum gravity, here represented as causal dynamical triangulations (CDT). The 2d CDT is known to provide a regularization of (Euclidean) 2d Hořava–Lifshitz quantum gravity.

Global Infinite Energy Solutions for the 2D Gravity Water Waves System [PDF]
, 2015 We prove global existence and a modified scattering property for the solutions of the 2D gravity water waves system in the infinite depth setting for a class of initial data, which is only required to be small above the level H˙1/5×H˙1/5+1/2 .

2D GRAVITY AND MATRIX MODELS I: 2D GRAVITY [PDF]
International Journal of Modern Physics A, 1994 Some approaches to 2D gravity which have been developed in the last few years are reviewed. They are physical (Liouville) gravity, topological theories and matrix models. Special attention is paid to matrix models and their interrelations with different approaches. Almost all technical details are omitted, but examples are presented.

No Page curves for the de Sitter horizon
Journal of High Energy Physics, 2022 We investigate the fine-grained entropy of the de Sitter cosmological horizon. Starting from three-dimensional pure de Sitter space, we consider a partial reduction approach, which supplies an auxiliary system acting as a heat bath both at I $$ \mathcal ...

Gravity as an ensemble and the moment problem
Journal of High Energy Physics, 2021 If a bulk gravitational path integral can be identified with an average of partition functions over an ensemble of boundary quantum theories, then a corresponding moment problem can be solved. We review existence and uniqueness criteria for the Stieltjes
