Classical Hamiltonian of Reissner-Nordström black holes at second post-Minkowskian order from scattering amplitudes
Allan Alonzo-Artiles, Manfred Kraus
We employ scattering amplitudes in Einstein-Maxwell theory to compute the classical Hamiltonian of a binary system of two charged, non-spinning compact objects. The effective Hamil…
First Look at Quartic-in-Spin Binary Dynamics at Third Post-Minkowskian Order
Dogan Akpinar, Fernando Febres Cordero, Manfred Kraus +2
We compute the conservative and radiation-reaction contributions to classical observables in the gravitational scattering between a spinning and a spinless black hole to the fourth…
Gravitational Bremsstrahlung in Black-Hole Scattering at : Quadratic-in-Spin Effects
Lara Bohnenblust, Harald Ita, Manfred Kraus +1
We are employing a supersymmetric variant of the worldline quantum field theory (WQFT) formalism to compute the far-field momentum-space gravitational waveform emitted during the s…
Spinning Black Hole Scattering at : Casimir Terms, Radial Action and Hidden Symmetry
Dogan Akpinar, Fernando Febres Cordero, Manfred Kraus +2
We resolve subtleties in calculating the post-Minkowskian dynamics of binary systems, as a spin expansion, from massive scattering amplitudes of fixed finite spin. In particular, t…
