Asymptotic Simplicity and Scattering in General Relativity from Quantum Field Theory
Stefano De Angelis, Aidan Herderschee, Radu Roiban +1
We investigate the fate of asymptotic simplicity in physically relevant settings of compact-object scattering. Using the stress tensor of a two-body system as a source, we compute…
Observables and Unconstrained Spin Tensor Dynamics in General Relativity from Scattering Amplitudes
Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4
In a previous Letter, we showed that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tens…
Conservative Spin Magnitude Change in Orbital Evolution in General Relativity
Mark Alaverdian, Zvi Bern, Dimitrios Kosmopoulos +4
We show that physical scattering observables for compact spinning objects in general relativity can depend on additional degrees of freedom in the spin tensor beyond those describe…
Difference Equations and Integral Families for Witten Diagrams
Mark Alaverdian, Aidan Herderschee, Radu Roiban +1
We show that tree-level and one-loop Mellin space correlators in anti-de Sitter space obey certain difference equations, which are the direct analog to the differential equations f…
Gravitational Waveform: A Tale of Two Formalisms
Donato Bini, Thibault Damour, Stefano De Angelis +4
We revisit the quantum-amplitude-based derivation of the gravitational waveform emitted by the scattering of two spinless massive bodies at the third order in Newton's constant, $h…
