Anti-scrambling and euclidean folds from observer correlators in de Sitter space
Daniel Harlow, Ying Zhao
The paper investigates how correlation functions measured by an observer in de Sitter space exhibit an anti‑scrambling behavior, contrasting with typical many‑body systems, and sug…
Holographic Black Hole Formation and Scrambling in Time-Ordered Correlators
Pratyusha Chowdhury, Felix M. Haehl, Adrián Sánchez-Garrido +1
We describe a holographic mechanism for black hole formation via the collision of two shock waves in three-dimensional anti-de Sitter spacetime. In the dual conformal field theory…
De Sitter quantum gravity and the emergence of local algebras
Molly Kaplan, Donald Marolf, Xuyang Yu +1
Quantum theories of gravity are generally expected to have some degree of non-locality, with familiar local physics emerging only in a particular limit. Perturbative quantum gravit…
"It from Bit": The Hartle-Hawking state and quantum mechanics for de Sitter observers
Ying Zhao
The one-state statement for closed universes has sparked considerable discussion. In this paper, we examine its physical meaning in the context of the Hartle-Hawking state and de S…
Closed universes, factorization, and ensemble averaging
Mykhaylo Usatyuk, Ying Zhao
We study closed universes in holographic theories of quantum gravity. We argue that within any fixed theory, factorization implies there is one unique closed universe state. The wa…
Quantum mechanics and observers for gravity in a closed universe
Daniel Harlow, Mykhaylo Usatyuk, Ying Zhao
Recent arguments based on the quantum extremal surface formula or the gravitational path integral have given fairly compelling evidence that the Hilbert space of quantum gravity in…
