Black Hole Response Theory and its Exact Shockwave Limit
Lara Bohnenblust, Carl Jordan Eriksen, Jitze Hoogeveen +2
We present a black hole response formalism formulated within the worldline approach to the classical gravitational two-body problem. The central objects are response functions: a h…
Gravitational scattering amplitudes from curved space
Carl Jordan Eriksen
Motivated by the study of extreme mass-ratio binary systems, recent work has explored the use of curved backgrounds in computations of classical gravitational amplitudes [arXiv:230…
The gravitational Compton amplitude at third post-Minkowskian order
N. Emil J. Bjerrum-Bohr, Gang Chen, Carl Jordan Eriksen +1
We employ a single worldline effective field theory in a Schwarzschild--Tangherlini background to compute the gravitational Compton amplitude up to third post-Minkowskian order. By…
The gravitational Compton amplitude from flat and curved spacetimes at second post-Minkowskian order
N. Emil J. Bjerrum-Bohr, Gang Chen, Carl Jordan Eriksen +1
We utilize various computational techniques in flat and curved backgrounds to calculate the classical gravitational Compton amplitude up to the second post-Minkowskian order. Our n…
