Effective Field Theory for Holographic Compact Objects
Miguel Correia, Vasco Gonçalves, Filipe Serrano
We study heavy-heavy-light-light correlators in holographic CFTs when the heavy operator is dual to a compact object localized on scales much smaller than the AdS radius. In the lo…
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…
Gravitational Wave Scattering via the Born Series: Scalar Tidal Matching to and Beyond
Simon Caron-Huot, Miguel Correia, Giulia Isabella +1
We introduce a novel method to compute gravitational wave amplitudes within the framework of effective field theory. By reinterpreting the Feynman diagram expansion as a Born serie…
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 Born regime of gravitational amplitudes
Miguel Correia, Giulia Isabella
We study the scattering in the regime where the wavelength of the scattered objects is comparable to their distance but is much larger than any Compton wavelength in the…
Recursive Landau Analysis
Simon Caron-Huot, Miguel Correia, Mathieu Giroux
We propose a recursive method that makes use of the basic principle of unitarity to calculate the Landau singularities of n-point scattering amplitudes directly in kinematic space.…
