Seeing Page Curves and Islands with Blinders On
Hao Geng, Andreas Karch, Carlos Perez-Pardavila +3
This paper summarizes recent discussions of the Page curve and the information paradox, and responds to the reasoning and examples from arXiv:2506.04311. We review arguments demons…
A model of errors in transformers
Suvrat Raju, Praneeth Netrapalli
We study the error rate of LLMs on tasks like arithmetic that require a deterministic output, and repetitive processing of tokens drawn from a small set of alternatives. We argue t…
Cosmological correlators in gravitationally-constrained de Sitter states
Tuneer Chakraborty, Ashik H, Suvrat Raju
We study cosmological correlators in de Sitter quantum gravity in the limit where . This limit is distinct from a nongravitational QFT because the gravitational constrai…
Holographic observers for time-band algebras
Kristan Jensen, Suvrat Raju, Antony J. Speranza
We study the algebra of observables in a time band on the boundary of anti-de Sitter space in a theory of quantum gravity. Strictly speaking this algebra does not have a commutant…
How does information emerge from a black hole?
Suvrat Raju
An examination of the constraints of quantum gravity leads to a clear physical picture for how information about the initial state is transferred to the Hawking radiation that emer…
Interacting Fields at Spatial Infinity
Anupam A. H, P. V. Athira, Priyadarshi Paul +1
We study the properties of massive fields extrapolated to the blowup of spatial infinity (), extending the program initiated in arXiv:2207.06406. In the free theory, we…
