Classical Gravitational Observables from the Eikonal Operator
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo +1
We propose two possible eikonal operators encoding the effects of classical radiation as coherent states of gravitons and show how to compute from them different classical observab…
The eikonal operator at arbitrary velocities I: the soft-radiation limit
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo +1
Observables related to the real part of the gravitational eikonal, such as the deflection angle and time delay, have been found so far to have a smooth post-Minkowskian (PM) expans…
Angular momentum of zero-frequency gravitons
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo
By following closely Weinberg's soft theorem, which captures the pole contribution to the amplitude for soft graviton emissions () on top of an arbitrary background hard…
