We review constructions of three-dimensional 'quantum'black holes. Such spacetimes arise
via holographic braneworlds and are exact solutions to an induced higher-derivative theory …

A bstract We develop a new setting in the framework of braneworld holography to describe a
pair of coupled and entangled uniformly accelerated universes. The model consists of two …

A bstract We study the semi-classical thermodynamics of two-dimensional de Sitter space
(dS 2) in Jackiw-Teitelboim (JT) gravity coupled to conformal matter. We extend the quasi …

A bstract In this paper, we study the von Neumann entropy of Hawking radiation SR for a d+
2-dimensional Hyperscaling Violating (HV) black brane which is coupled to two Minkowski …

The Fabbri–Russo model is a generalized model of a two-dimensional dilaton gravity theory
with various parameters “n” describing various specific gravities. Particularly, the Russo …

A bstract Entanglement islands play a crucial role in our understanding of how Hawking
radiation encodes information in a black hole, but their relevance in cosmological …

We obtain the holographic entanglement negativity for bipartite mixed states at a finite
temperature in baths described by conformal field theories dual to configurations involving …

A bstract Quantum extremal surfaces (QES), codimension-2 spacelike regions which
extremize the generalized entropy of a gravity-matter system, play a key role in the study of …

The island paradigm for the fine-grained entropy of Hawking radiation is applied to eternal
charged accelerating black holes. In the absence of the island, the entanglement entropy …

We propose a doubly holographic version of the semiclassical island formula for the
entanglement negativity in the framework of the defect AdS/BCFT correspondence where …
