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 …

We introduce a new quantity, called pseudo-entropy, as a generalization of entanglement
entropy via postselection. We expect this quantity to provide a new class of order parameters …

We review the various aspects of the 3D Einstein gravity theory with a negative cosmological
constant and its boundary description. We also explore its connections to conformal field …

We study various aspects of capacity of entanglement in the squeezed states of a scalar field
theory. This quantity is a quantum informational counterpart of heat capacity and …

We provide a consistent first principles prescription to compute gravitational Rényi entropy
using Hayward corner terms. For Euclidean solutions to Einstein gravity, we compute Rényi …

A bstract We present a new derivation of gravitational entropy functionals in higher-curvature
theories of gravity using corner terms that are needed to ensure well-posedness of the …

A bstract We study the Hayward term describing corners in the boundary of the geometry in
the context of the Jackiw-Teitelboim gravity. These corners naturally arise in the computation …

Motivated by extended black hole thermodynamics, we generalize the Rényi entropy of
charged holographic conformal field theories (CFTs) in d-dimensions. Specifically, following …

We introduce a quantity, called pseudo entropy, as a generalization of entanglement entropy
via post-selection. In the AdS/CFT correspondence, this quantity is dual to areas of minimal …
