The Schwarzian theory — origins [PDF]
Journal of High Energy Physics, 2018 In this paper we further study the 1d Schwarzian theory, the universal low-energy limit of Sachdev-Ye-Kitaev models, using the link with 2d Liouville theory.

Generalized dilaton gravity in 2d [PDF]
SciPost Physics, 2022 Generalized dilaton gravity in 2d is the most general consistent deformation of the Jackiw-Teitelboim model that maintains local Lorentz invariance. The action is generically not power-counting renormalizable, thus going beyond the class of models ...

SciPost Physics, 2023 We present a quantitative and fully non-perturbative description of the ergodic phase of quantum chaos in the setting of two-dimensional gravity. To this end we describe the doubly non-perturbative completion of semiclassical 2D gravity in terms of its ...

Revisit on holographic complexity in two-dimensional gravity
Journal of High Energy Physics, 2020 We revisit the late-time growth rate of various holographic complexity conjectures for neutral and charged AdS black holes with single or multiple horizons in two dimensional (2D) gravity like Jackiw-Teitelboim (JT) gravity and JT-like gravity.

Journal of High Energy Physics, 2023 We present a JT gravity set up in the presence of projected ModMax corrections in two dimensions. Our starting point is the Einstein’s gravity in four dimensions accompanied by the ModMax Lagrangian. The 2D gravity action is obtained following a suitable

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

On the relation between Euclidean and Lorentzian 2D quantum gravity [PDF]
, 1999 Starting from 2D Euclidean quantum gravity, we show that one recovers 2D Lorentzian quantum gravity by removing all baby universes. Using a peeling procedure to decompose the discrete, triangulated geometries along a one-dimensional path, we explicitly ...

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

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.
