We review recent developments in Jackiw–Teitelboim gravity. This is a simple solvable
model of quantum gravity in two dimensions (that arises eg from the s-wave sector of higher …

In this review, recent progress on the black hole information problem that involves a new
understanding of how to calculate the entropy of Hawking radiation is described. The review …

The holographic principle, theorized to be a property of quantum gravity, postulates that the
description of a volume of space can be encoded on a lower-dimensional boundary. The …

We propose a measure of quantum state complexity defined by minimizing the spread of the
wave function over all choices of basis. Our measure is controlled by the “survival amplitude” …

A bstract The information paradox can be realized in anti-de Sitter spacetime joined to a
Minkowski region. In this setting, we show that the large discrepancy between the von …

A bstract Recent work has shown how to obtain the Page curve of an evaporating black hole
from holographic computations of entanglement entropy. We show how these computations …

A bstract We construct a Type II∞ von Neumann algebra that describes the large N physics
of single-trace operators in AdS/CFT in the microcanonical ensemble, where there is no …

The Swampland program aims to distinguish effective theories which can be completed into
quantum gravity in the ultraviolet from those which cannot. This article forms an introduction …

A bstract When absorbing boundary conditions are used to evaporate a black hole in
AdS/CFT, we show that there is a phase transition in the location of the quantum Ryu …

A bstract Recently Leutheusser and Liu [1, 2] identified an emergent algebra of Type III 1 in
the operator algebra of\(\mathcal {N}\)= 4 super Yang-Mills theory for large N. Here we …
