Mutual Information in spacetime

Raúl E. Arias, Marina Huerta, Pedro J. Martinez

We compute mutual information for general spacetime regions using Sorkin's Gaussian field formalism. We show that this construction is naturally based on the reduced space of smear…

Microcanonical Energy Sharing and a Page-like Curve for the Capacity of Entanglement

Raul Arias

We study the capacity of entanglement in the microcanonical ensemble for an effectively additive bipartite system. Using typicality and the block structure of the microcanonical re…

Probing the Factorized Island Branch with the Capacity of Entanglement in JT Gravity

Raúl Arias, Agustín Tamis

Black hole islands are usually diagnosed through the von Neumann entropy, but the full replica saddle contains more information than survives in the limit . In this paper…

Capacity of Entanglement and Replica Backreaction in RST Gravity

Raúl Arias, Daniel Fondevila

We compute the capacity of entanglement in two dimensional dilaton gravity in a setting where Hawking radiation, backreaction, and islands can be treated analytically. Our focus is…

Real-time methods in JT/SYK holography

Raúl Arias, Marcelo Botta-Cantcheff, Pedro J. Martinez

We study the conventional holographic recipes and its real-time extensions in the context of the correspondence between SYK quantum mechanics and JT gravity. We first observe that…

Entanglement in the Quantum Spherical Model -- a Review

Sascha Wald, Raul Arias, Vincenzo Alba

We review some recent results on entanglement in the Quantum Spherical Model (QSM). The focus lays on the physical results rather than the mathematical details. Specifically, we st…
