Amplitudes for Hawking Radiation
Rafael Aoude, Donal O'Connell, Matteo Sergola
We obtain the Hawking spectrum by exponentiating a series of Feynman diagrams describing a scalar field scattering through a collapse background. Our approach is rooted in semiclas…
Inelastic Coupled-Channel Eikonal Scattering
Rafael Aoude, Andrea Cristofoli, Asaad Elkhidir +1
Emitted radiation and absorption effects in black hole dynamics lead to inelastic scattering amplitudes. In this paper, we study how these effects introduce an inelasticity functio…
Positivity in Amplitudes and Quantum Entanglement
Rafael Aoude, Gilly Elor, Grant N. Remmen +1
We explore the connection of positivity of the imaginary part of forward elastic amplitudes for perturbative scattering with consistency of the entanglement generated by the S-matr…
