Hawking radiation from the double copy
Anton Ilderton, William Lindved, Karthik Rajeev
Gravity and gauge theory are concretely linked by the double copy. Although well-studied at the level of perturbative scattering in vacuum, far less is known about non-perturbative…

Coherent states, background fields, and double copy
Anton Ilderton, William Lindved
We show that scattering amplitudes on any gauge theory background admitting a coherent state description double copy to amplitudes in a curved spacetime. The metric of the spacetim…

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…
