Lessons from the information paradox
S Raju - Physics Reports, 2022 - Elsevier
We review recent progress on the information paradox. We explain why exponentially small
correlations in the radiation emitted by a black hole are sufficient to resolve the original …

The Page curve of Hawking radiation from semiclassical geometry
A bstract We consider a gravity theory coupled to matter, where the matter has a higher-
dimensional holographic dual. In such a theory, finding quantum extremal surfaces becomes …

Transcending the ensemble: baby universes, spacetime wormholes, and the order and disorder of black hole information
A bstract In the 1980's, work by Coleman and by Giddings and Strominger linked the physics
of spacetime wormholes to 'baby universes' and an ensemble of theories. We revisit such …

Emergent times in holographic duality
S Leutheusser, H Liu - Physical Review D, 2023 - APS
In holographic duality an eternal Anti-de Sitter black hole is described by two copies of the
boundary Conformal Field Theory in the thermal field double state. In this paper we provide …
