Wormholes in 2d Horǎva-Lifshitz quantum gravity

open access: yesPhysics Letters B, 2021
We quantize the two-dimensional projectable Horǎva-Lifshitz gravity with a bi-local as well as space-like wormhole interaction. The resulting quantum Hamiltonian coincides with the one obtained through summing over all genus in the string field theory ...

What is the curvature of 2D Euclidean quantum gravity? [PDF]

open access: yesJournal of High Energy Physics
Abstract We re-examine the nonperturbative curvature properties of two-dimensional Euclidean quantum gravity, obtained as the scaling limit of a path integral over dynamical triangulations of a two-sphere, which lies in the same universality class as Liouville quantum gravity.

Matrix models of 2d gravity [PDF]

open access: yes, 1991
These are introductory lectures for a general audience that give an overview of the subject of matrix models and their application to random surfaces, 2d gravity, and string theory. They are intentionally 1.5 years out of date. 0. Canned Diatribe, Introduction, and Apologies 1. Discretized surfaces, matrix models, and the continuum limit 2.

Revisit on holographic complexity in two-dimensional gravity

open access: yesJournal 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.

AdS 2 holography and ModMax

open access: yesJournal 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

open access: yesJournal 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

The Cardy–Verlinde formula for 2D gravity [PDF]

open access: yesNuclear Physics B, 2002
We discuss the different bounds on entropy in the context of two-dimensional cosmology. We show that in order to obtain well definite bounds one has to use the scale symmetry of the gravitational theory. We then extend the recently found relation between the Friedmann equation and the Cardy formula to the case of two dimensions.

Effective gravitational action for 2D massive fermions

open access: yesJournal of High Energy Physics, 2021
We work out the effective gravitational action for 2D massive Euclidean fermions in a small mass expansion. Besides the leading Liouville action, the order m 2 gravitational action contains a piece characteristic of the Mabuchi action, much as for 2D ...
