Hawking Radiation meets the Double Copy
Rafael Aoude, Donal O'Connell, Matteo Sergola +1
We describe an electromagnetic system which is related to black hole production with Hawking radiation through the double copy. We consider the scattering of a massless scalar part…
Quantum Effects for Black Holes with On-Shell Amplitudes
Katsuki Aoki, Andrea Cristofoli, Hyun Jeong +2
We develop a framework based on modern amplitude techniques to analyze emission and absorption effects in black hole physics, including Hawking radiation. We first discuss quantum…
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…
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…
Post-Newtonian observables for aligned-spin binaries to sixth order in spin from gravitational self-force and Compton amplitudes
Yilber Fabian Bautista, Mohammed Khalil, Matteo Sergola +2
Accurate modeling of compact binaries is essential for gravitational-wave detection and parameter estimation, with spin being an important effect to include in waveform models. In…
The Uncertainty Principle and Classical Amplitudes
Andrea Cristofoli, Riccardo Gonzo, Nathan Moynihan +4
We study the variance in the measurement of observables during scattering events, as computed using amplitudes. The classical regime, characterised by negligible uncertainty, emerg…
