Quantum State of a Gravitating Region
Raphael Bousso, Sami Kaya, Guanda Lin +1
We propose that any compact -manifold with elliptic data, , prepares a quantum state on its -boundary . Elliptic data consists of m…
Consistent Evaluation of the No-Boundary Proposal
Ahmed I. Abdalla, Stefano Antonini, Raphael Bousso +3
We revisit the Hartle-Hawking no-boundary proposal. To extract probabilities, one must use the gravitational path integral (GPI) to compute not only the no-boundary amplitude, but…
Discrete Max-Focusing
Raphael Bousso, Elisa Tabor
The Quantum Focusing Conjecture (QFC) lies at the foundation of holography and semiclassical gravity. The QFC implies the Bousso bound and the Quantum Null Energy Condition (QNEC).…
Fundamental Complement of a Gravitating Region
Raphael Bousso, Sami Kaya
Any gravitating region in any spacetime gives rise to a generalized entanglement wedge, the hologram . Holograms exhibit properties expected of fundamental operator algeb…
Simple Holography in General Spacetimes
Raphael Bousso, Elisa Tabor
The simple or "outermost" wedge in AdS is the portion of the entanglement wedge that can be reconstructed with sub-exponential effort from CFT data. Here we furnish a definition in…
Firewalls From General Covariance
Raphael Bousso
I define "horizon normalcy" as the approximate validity of Semiclassical Gravity and Effective Field Theory (SGEFT), for the description of observers that approach or cross a black…
