Quantum chaos in 2D gravity [PDF]

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 ...

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 ...

Islands in asymptotically flat 2D gravity [PDF]

Journal of High Energy Physics, 2020
The large-N limit of asymptotically flat two-dimensional dilaton gravity coupled to N free matter fields provides a useful toy model for semiclassical black holes and the information paradox.

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.

Gravity dual of two-dimensional N $$ \mathcal{N} $$ = (2, 2)∗ supersymmetric Yang-Mills theory and integrable models

Journal of High Energy Physics, 2018
The 2D N $$ \mathcal{N} $$ = (2, 2)∗ supersymmetric Yang-Mills theory can be obtained from the 2D N $$ \mathcal{N} $$ = (4, 4) theory with a twisted mass deformation.

SYK correlators from 2D Liouville-de Sitter gravity

Journal of High Energy Physics
We introduce and study a candidate gravity dual to the double scaled SYK model in the form of an exactly soluble 2D de Sitter gravity model consisting of two spacelike Liouville CFTs with complex central charge adding up to c + + c − = 26.

The relation between Euclidean and Lorentzian 2D quantum gravity [PDF]

, 2000
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 ...

A 2D model of Causal Set Quantum Gravity: The emergence of the continuum

, 2007
Non-perturbative theories of quantum gravity inevitably include configurations that fail to resemble physically reasonable spacetimes at large scales.

An entropic puzzle in periodic dilaton gravity and DSSYK

Journal of High Energy Physics
We study 2d dilaton gravity theories with a periodic potential, with special emphasis on sine dilaton gravity, which is holographically dual to double-scaled SYK.
