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 …

S Chapman, G Policastro - The European Physical Journal C, 2022 - Springer
Quantum computational complexity estimates the difficulty of constructing quantum states
from elementary operations, a problem of prime importance for quantum computation …

Inconsistency of islands in theories with long-range gravity

H Geng, A Karch, C Perez-Pardavila, S Raju… - Journal of High Energy …, 2022 - Springer
A bstract In ordinary gravitational theories, any local bulk operator in an entanglement

the Page curve of the eternal Reissner-Nordström black holes in four dimensions ignoring …

Island in charged black holes

Y Ling, Y Liu, ZY Xian - Journal of High Energy Physics, 2021 - Springer
A bstract We study the information paradox for the eternal black hole with charges on a
doubly-holographic model in general dimensions, where the charged black hole on a …

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 …

Entangled universes in dS wedge holography

SE Aguilar-Gutierrez, AK Patra, JF Pedraza - Journal of High Energy …, 2023 - Springer
A bstract We develop a new setting in the framework of braneworld holography to describe a
pair of coupled and entangled uniformly accelerated universes. The model consists of two …

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 …
