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, AgustÃn 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…
