Pair creation, backreaction, and resummation in strong fields
Patrick Copinger, James P. Edwards, Anton Ilderton +1
We revisit particle creation in strong fields, and backreaction on those fields, from an amplitudes perspective. We describe the strong field by an initial coherent state of photon…
Vacuum polarisation effects in impulsive fields
Anton Ilderton, Hannah Kingham
Photons impinging on strong electromagnetic fields can change both momentum and helicity state, due to quantum vacuum polarisation. We investigate these effects in the collision of…
All-multiplicity amplitudes in impulsive PP-waves from the worldline formalism
Patrick Copinger, James P. Edwards, Anton Ilderton +1
We use the worldline formalism to derive Bern-Kosower type Master Formulae for the tree-level scattering of a charged particle and an arbitrary number of photons on impulsive PP-wa…
Toward double copy on arbitrary backgrounds
Anton Ilderton, William Lindved
Double copy relates scattering amplitudes in a web of gravitational and gauge theories. Although it has seen great success when applied to amplitudes in vacuum, far less is known a…
Gravitational Bound Waveforms from Amplitudes
Tim Adamo, Riccardo Gonzo, Anton Ilderton
With the aim of computing bound waveforms from scattering amplitudes, we explore gravitational two-body dynamics using the Schwinger-Dyson equations and Bethe-Salpeter recursion. W…
