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…
