Killing Horizons Decohere Quantum Superpositions
Daine L. Danielson, Gautam Satishchandran, Robert M. Wald
We recently showed that if a massive (or charged) body is put in a quantum spatial superposition, the mere presence of a black hole in its vicinity will eventually decohere the sup…
Local and Covariant Flow Relations for OPE Coefficients in Lorentzian Spacetimes
Mark G. Klehfoth, Robert M. Wald
For Euclidean quantum field theories, Holland and Hollands have shown operator product expansion (OPE) coefficients satisfy "flow equations": For interaction parameter , the par…
Cross-Section Continuity of Definitions of Angular Momentum
Po-Ning Chen, Daniel Paraizo, Robert M. Wald +3
We introduce a notion of "cross-section continuity" as a criterion for the viability of definitions of angular momentum, , at null infinity: If a sequence of cross-sections, ${\…
Black Holes Decohere Quantum Superpositions
Daine L. Danielson, Gautam Satishchandran, Robert M. Wald
We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destro…
Infrared Finite Scattering Theory in Quantum Field Theory and Quantum Gravity
Kartik Prabhu, Gautam Satishchandran, Robert M. Wald
Infrared (IR) divergences arise in scattering theory with massless fields and are manifestations of the memory effect. There is nothing singular about states with memory, but they…
Gravitationally Mediated Entanglement: Newtonian Field vs. Gravitons
Daine L. Danielson, Gautam Satishchandran, Robert M. Wald
We argue that if the Newtonian gravitational field of a body can mediate entanglement with another body, then it should also be possible for the body producing the Newtonian field…
