Capacity of entanglement for scalar fields in squeezed states

MR Mohammadi Mozaffar - Physical Review D, 2024 - APS
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 …

Encoded information of mixed correlations: the views from one dimension higher

M Ghodrati - Journal of High Energy Physics, 2023 - Springer
A bstract After reviewing the JT gravity, we discuss the four saddles in the mixed correlation
measures of black holes Hawking radiation in the setup of geometric evaporation of [1]. By …

Gravitational Rényi entropy from corner terms

J Kastikainen, A Svesko - Physical Review D, 2024 - APS
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 …

Cornering gravitational entropy

J Kastikainen, A Svesko - Journal of High Energy Physics, 2024 - Springer
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 …

Half-sided Translations and Islands

K Jalan, R Pius - arXiv preprint arXiv:2312.11085, 2023 - arxiv.org
Recently Liu and Leutheusser argued that the operators in the interior of a black hole can be
reconstructed by the half-sided evolution of the non-local operators in the boundary CFT …

Real-time methods in JT/SYK holography

R Arias, M Botta-Cantcheff… - Classical and Quantum …, 2024 - iopscience.iop.org
We study the conventional holographic recipes and its real-time extensions in the context of
the correspondence between Sachdev–Ye–Kitaev quantum mechanics and JT gravity. We …
