Quantum Field Theory, Worldline Theory, and Spin Magnitude Change in Orbital Evolution
Zvi Bern, Dimitrios Kosmopoulos, Andres Luna +4
A previous paper~\cite{Bern:2022kto} identified a puzzle stemming from the amplitudes-based approach to spinning bodies in general relativity: additional Wilson coefficients appear…
Scattering Angles in Kerr Metrics
Poul H. Damgaard, Jitze Hoogeveen, Andres Luna +1
Scattering angles for probes in Kerr metrics are derived for scattering in the equatorial plane of the black hole. We use a method that naturally resums all orders in the spin of t…
Why is the Weyl double copy local in position space?
Andres Luna, Nathan Moynihan, Chris D. White
The double copy relates momentum-space scattering amplitudes in gauge and gravity theories. It has also been extended to classical solutions, where in some cases an exact double co…
Binary Dynamics Through the Fifth Power of Spin at
Zvi Bern, Dimitrios Kosmopoulos, Andrés Luna +2
We use a previously developed scattering-amplitudes-based framework for determining two-body Hamiltonians for generic binary systems with arbitrary spin . By construction this f…
Scalar QED as a toy model for higher-order effects in classical gravitational scattering
Zvi Bern, Juan Pablo Gatica, Enrico Herrmann +2
Quantum Electrodynamics (QED) serves as a useful toy model for classical observables in gravitational two-body systems with reduced complexity due to the linearity of QED. We inves…
The double copy of the multipole expansion
Erick Chacón, Andres Luna, Chris D. White
We consider the classical double copy, that relates solutions of biadjoint scalar, gauge and gravity theories. Using a recently developed twistor expression of this idea, we use we…
