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 ...

Scale-dependent Hausdorff dimensions in 2d gravity
Physics Letters B, 2014 By appropriate scaling of coupling constants a one-parameter family of ensembles of two-dimensional geometries is obtained, which interpolates between the ensembles of (generalized) causal dynamical triangulations and ordinary dynamical triangulations ...

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

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.

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.

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.

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 ...
