Environmental Effects in Post-Minkowskian Dynamics: Effective Field Theory, Feynman Rules, and Ward Identities for Compact Objects in Relativistic Fluids
Zvi Bern, Samuel Degen, Enrico Herrmann +2
We develop a hydrodynamic effective field theory for the gravitational dynamics of compact objects moving through an inviscid fluid environment. The fluid is described by the effec…
Gravitational Compton Amplitude to All Orders in Perturbation Theory
Miguel Correia, Giulia Isabella, Anna M. Wolz
We show how amplitudes from the scattering of gravitational waves off compact objects in worldline effective field theory can be efficiently computed to arbitrary order in Newton's…
Analyticity of the Black Hole S-Matrix
Miguel Correia, Tushar Gopalka, Giulia Isabella +1
We establish the analytic structure of the S-matrix in the complex-frequency plane for classical wave scattering on a Schwarzschild background in four space-time dimensions. Our ar…
Records from the S-Matrix Marathon: Gravitational Physics from Scattering Amplitudes
Miguel Correia, Holmfridur S. Hannesdottir, Giulia Isabella +5
These lecture notes explain how classical gravitational physics emerges from scattering amplitudes. We emphasize the role of different kinematic regimes in probing various aspects…
The hierarchical three-body problem at
Mikhail P. Solon, Anna M. Wolz
Employing techniques from scattering amplitudes and effective field theory, we model the dynamics of hierarchical triples, which are three-body systems composed of two bodies separ…
