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…
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…
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…
Holography of information in de Sitter space
Tuneer Chakraborty, Joydeep Chakravarty, Victor Godet +2
We study the natural norm on the space of solutions to the Wheeler-DeWitt equation in an asymptotically de Sitter spacetime. We propose that the norm is obtained by integrating the…
The Hilbert space of de Sitter quantum gravity
Tuneer Chakraborty, Joydeep Chakravarty, Victor Godet +2
We obtain solutions of the Wheeler-DeWitt equation with positive cosmological constant for a closed universe in the large-volume limit. We argue that this space of solutions provid…
