The entropy of Hawking radiation

A Almheiri, T Hartman, J Maldacena… - Reviews of Modern …, 2021 - APS
In this review, recent progress on the black hole information problem that involves a new
understanding of how to calculate the entropy of Hawking radiation is described. The review …

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 …

Replica wormholes and the entropy of Hawking radiation

A Almheiri, T Hartman, J Maldacena… - Journal of High Energy …, 2020 - Springer
A bstract The information paradox can be realized in anti-de Sitter spacetime joined to a
Minkowski region. In this setting, we show that the large discrepancy between the von …

Replica wormholes and the black hole interior

G Penington, SH Shenker, D Stanford… - Journal of High Energy …, 2022 - Springer
A bstract Recent work has shown how to obtain the Page curve of an evaporating black hole
from holographic computations of entanglement entropy. We show how these computations …

The Page curve of Hawking radiation from semiclassical geometry

A Almheiri, R Mahajan, J Maldacena… - Journal of High Energy …, 2020 - Springer
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 …

Entanglement wedge reconstruction and the information paradox

G Penington - Journal of High Energy Physics, 2020 - Springer
A bstract When absorbing boundary conditions are used to evaporate a black hole in
AdS/CFT, we show that there is a phase transition in the location of the quantum Ryu …

The black hole interior from non-isometric codes and complexity

C Akers, N Engelhardt, D Harlow, G Penington… - Journal of High Energy …, 2024 - Springer
A bstract Quantum error correction has given us a natural language for the emergence of
spacetime, but the black hole interior poses a challenge for this framework: at late times the …

Islands in cosmology

T Hartman, Y Jiang, E Shaghoulian - Journal of High Energy Physics, 2020 - Springer
A bstract A quantum extremal island suggests that a region of spacetime is encoded in the
quantum state of another system, like the encoding of the black hole interior in Hawking …

Entanglement wedge reconstruction via universal recovery channels

J Cotler, P Hayden, G Penington, G Salton, B Swingle… - Physical Review X, 2019 - APS
In the context of quantum theories of spacetime, one overarching question is how quantum
information in the bulk spacetime is encoded holographically in boundary degrees of …

Leading order corrections to the quantum extremal surface prescription

C Akers, G Penington - Journal of High Energy Physics, 2021 - Springer
A bstract We show that a naïve application of the quantum extremal surface (QES)
prescription can lead to paradoxical results and must be corrected at leading order. The …
