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…
Resumming Spinning Black Hole Dynamics at Third Post-Minkowskian Order
N. Emil J. Bjerrum-Bohr, Gang Chen, Konstantinos Papadimos +1
We investigate the relativistic scattering of spinning black holes using modern amplitude methods within a heavy-mass effective field theory formalism at third post-Minkowskian ord…
Kerr Black Hole Dynamics from an Extended Polyakov Action
N. Emil J. Bjerrum-Bohr, Gang Chen, Chenliang Su +1
We examine a hypersurface model for the classical dynamics of spinning black holes. Under specific rigid geometric constraints, it reveals an intriguing solution resembling expecta…
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…
