Canonical Quantisation of Bound and Unbound WQFT
Riccardo Gonzo, Gustav Mogull
Using canonical quantisation, and eschewing the Schwinger-Keldysh path integral, we derive a version of the Worldline Quantum Field Theory (WQFT) formalism suitable for both scatte…
The Uncertainty Principle and Classical Amplitudes
Andrea Cristofoli, Riccardo Gonzo, Nathan Moynihan +4
We study the variance in the measurement of observables during scattering events, as computed using amplitudes. The classical regime, characterised by negligible uncertainty, emerg…
Waveforms from Amplitudes
Andrea Cristofoli, Riccardo Gonzo, David A. Kosower +1
We show how to compute classical wave observables using quantum scattering amplitudes. We discuss observables both with incoming and with outgoing waves. The required classical lim…
BMS Symmetry of Celestial OPE
Shamik Banerjee, Sudip Ghosh, Riccardo Gonzo
In this paper we study the BMS symmetry of the celestial OPE of two positive helicity gravitons in Einstein theory in four dimensions. The celestial OPE is obtained by Mellin trans…
