Bra-ket wormholes in gravitationally prepared states

open access: yesJournal 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.

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

open access: yesJournal 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.

No Page curves for the de Sitter horizon

open access: yesJournal 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 ...

Softening transitions with quenched 2D gravity [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1997
We perform extensive Monte Carlo simulations of the 10-state Potts model on quenched two-dimensional $Φ^3$ gravity graphs to study the effect of quenched connectivity disorder on the phase transition, which is strongly first order on regular lattices.

Combinatorial Quantum Gravity and Emergent 3D Quantum Behaviour

open access: yes, 2023
We review combinatorial quantum gravity, an approach that combines Einstein’s idea of dynamical geometry with Wheeler’s “it from bit” hypothesis in a model of dynamical graphs governed by the coarse Ollivier–Ricci curvature.

The two-sphere partition function in two-dimensional quantum gravity

open access: yesJournal of High Energy Physics, 2021
We study the Euclidean path integral of two-dimensional quantum gravity with positive cosmological constant coupled to conformal matter with large and positive central charge.

2D gravity+1D matter

open access: yesPhysics Letters B, 1990
Abstract We consider a formulation of nonperturbative two-dimensional quantum gravity coupled to a single bosonic field (d = 1 matter). Starting from a matrix realization of the discretized model, we express the continuum theory as a double scaling limit in which the 2D cosmological constant g tends towards a critical value gc, and the string ...

Effects of Gravity and Inlet/Outlet Location on a Two-Phase Cocurrent Imbibition in Porous Media

open access: yesJournal of Applied Mathematics, 2011
We introduce 2D numerical investigations of the problem of gravity and inlet/outlet location effects of water-oil two-phase cocurrent imbibition in a porous medium. Three different cases of side-, top-, and bottom-inlet location are considered.

The price of curiosity: information recovery in de Sitter space

open access: yesJournal of High Energy Physics, 2021
Recent works have revealed that quantum extremal islands can contribute to the fine-grained entropy of black hole radiation reproducing the unitary Page curve.

The Schwarzian theory — origins

open access: yesJournal 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.
