Holographic algebras at null infinity
Chang-Han Chen, Geoff Penington, Gautam Satishchandran +1
We construct an algebra of observables associated to a cut of null infinity in asymptotically flat spacetimes. The Bondi mass associated with a sharp cut of future null infinity is…
Uniqueness of null-local modular flow
Gautam Satishchandran, Jonathan Sorce
In arXiv:2306.01837, it was conjectured that one can engineer a large class of quantum field theory states for which the modular flow on a spacelike slice is "instantaneously local…
Generalized Entropy is von Neumann Entropy II: The complete symmetry group and edge modes
Marc S. Klinger, Jonah Kudler-Flam, Gautam Satishchandran
We consider the algebra of observables of perturbative quantum gravity in the exterior of a stationary black hole or the static patch of de Sitter spacetime. It was previously argu…
