Black Hole Thermodynamics Meets On-Shell Amplitudes: Local Detailed Balance and Thermal Spectrum from Spin Universality and Unitarity
Dogan Akpinar, Katsuki Aoki, Andrea Cristofoli +2
We develop an on-shell framework for thermal dissipation and radiation by macroscopic objects, whose large degeneracy of internal states is encoded in their entropy. In this framew…
Unexpected Symmetries of Kerr Black Hole Scattering
Dogan Akpinar, Graham R. Brown, Riccardo Gonzo +1
Motivated by the recent introduction of the Dirac bracket framework to compute spinning observables for the scattering of Kerr black holes, we initiate the study of conserved quant…
Scattering Gravitons off General Spinning Compact Objects to
Dogan Akpinar
We compute the classical one-loop gravitational Compton amplitude describing the scattering of a graviton off a massive spinning compact object at the second post-Minkowskian order…
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…
The spinning self-force EFT: 1SF waveform recursion relation and Compton scattering
Dogan Akpinar, Vittorio del Duca, Riccardo Gonzo
Building on recent approaches, we develop an effective field theory for the interaction of spinning particles modeling Kerr black holes within the gravitational self-force expansio…
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…
