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 …

Revisiting recent progress in the Karch-Randall braneworld

H Geng - arxiv preprint arxiv:2306.15671, 2023 - arxiv.org
Motivated by the study of entanglement island in the Karch-Randall braneworld, it has been
conjectured and proven in general that entanglement island is not consistent with long …

Information transfer with a gravitating bath

H Geng, A Karch, C Perez-Pardavila, S Raju… - SciPost Physics, 2021 - scipost.org
Late-time dominance of entanglement islands plays a critical role in addressing the
information paradox for black holes in AdS coupled to an asymptotic non-gravitational bath …

Bra-ket wormholes in gravitationally prepared states

Y Chen, V Gorbenko, J Maldacena - Journal of High Energy Physics, 2021 - Springer
We consider two dimensional CFT states that are produced by a gravitational path integral.
As a first case, we consider a state produced by Euclidean AdS2 evolution followed by flat …

BCFT and Islands in two dimensions

K Suzuki, T Takayanagi - Journal of High Energy Physics, 2022 - Springer
A bstract By combining the AdS/BCFT correspondence and the brane world holography, we
expect an equivalence relation between a boundary conformal field theory (BCFT) and a …

Jackiw-Teitelboim gravity from the Karch-Randall braneworld

H Geng, A Karch, C Perez-Pardavila, S Raju… - Physical Review Letters, 2022 - APS
In this Letter, we show that Jackiw-Teitelboim gravity can be naturally realized in the Karch-
Randall braneworld. Notably the role of the dilaton in Jackiw-Teitelboim gravity is played by …

Islands and Page curves in 4d from Type IIB

CF Uhlemann - Journal of High Energy Physics, 2021 - Springer
A bstract Variants of the black hole information paradox are studied in Type IIB string theory
setups that realize four-dimensional gravity coupled to a bath. The setups are string theory …

The central dogma and cosmological horizons

E Shaghoulian - Journal of High Energy Physics, 2022 - Springer
A bstract The central dogma of black hole physics—which says that from the outside a black
hole can be described in terms of a quantum system with exp (Area/4G N) states evolving …

Holographic BCFTs and communicating black holes

H Geng, S Lüst, RK Mishra, D Wakeham - Journal of High Energy Physics, 2021 - Springer
A bstract We study the AdS/BCFT duality between two-dimensional conformal field theories
with two boundaries and three-dimensional anti-de Sitter space with two Karch-Randall …

Entanglement entropy in a holographic moving mirror and the Page curve

I Akal, Y Kusuki, N Shiba, T Takayanagi, Z Wei - Physical review letters, 2021 - APS
We calculate the time evolution of entanglement entropy in two-dimensional conformal field
theory with a moving mirror. For a setup modeling Hawking radiation, we obtain a linear …
