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…

Gravitational algebras and the generalized second law
Thomas Faulkner, Antony J. Speranza
We derive the generalized second law (GSL) for arbitrary cuts of Killing horizons from the perspective of crossed-product gravitational algebras, making use of a recent proposal by…
