Asymptotic Charges Cannot Be Measured in Finite Time
Raphael Bousso, Venkatesa Chandrasekaran, Illan F. Halpern +1
To study quantum gravity in asymptotically flat spacetimes, one would like to understand the algebra of observables at null infinity. Here we show that the Bondi mass cannot be obs…
Decoding the Apparent Horizon: A Coarse-Grained Holographic Entropy
Netta Engelhardt, Aron C. Wall
When a black hole forms from collapse in a holographic theory, the information in the black hole interior remains encoded in the boundary. We prove that the area of the black hole'…
No Simple Dual to the Causal Holographic Information?
Netta Engelhardt, Aron C. Wall
In AdS/CFT, the fine grained entropy of a boundary region is dual to the area of an extremal surface X in the bulk. It has been proposed that the area of a certain 'causal surface'…
A Lower Bound on the Energy Density in Classical and Quantum Field Theories
Aron C. Wall
A novel method for deriving energy conditions in stable field theories is described. In a local classical theory with one spatial dimension, a local energy condition always exists.…
