Non-topological solitons in biadjoint scalar field theory
Kymani Armstrong-Williams, Chris D. White
Biadjoint scalar theory has been widely studied, due to its being closely related to the double copy correspondence linking gauge, gravity and related theories. In this paper, we c…
Classical strings and the double copy
Riccardo Morieri, Igor Pesando, Michael L. Reichenberg Ashby +1
The double copy is by now a well-established relationship between scattering amplitudes and classical solutions in gauge and gravity (field) theories, and is itself inspired by amp…
The double copy as a doppelgänger
Nathan Moynihan, Michael L. Reichenberg Ashby, Chris D. White
The double copy relates scattering amplitudes and classical solutions in non-abelian gauge theories and gravity. As such, it is usually expressed in the conventional second-order f…
Topological modes, non-locality and the double copy
William T. Emond, Laura Engelbrecht, Nathan Moynihan +1
The double copy connects scattering amplitudes and other objects in gauge and gravity theories. Open conceptual issues include whether non-local information in gravity theories can…
Time-dependent solutions of biadjoint scalar field theories
Kymani Armstrong-Williams, Chris D. White
Biadjoint scalar field theories appear in the study of scattering amplitudes and classical solutions in gauge, gravity and related theories. In this paper, we present new exact sol…
Deriving Weyl double copies with sources
Kymani Armstrong-Williams, Nathan Moynihan, Chris D. White
The Weyl double copy is a relationship between classical solutions in gauge and gravity theories, and has previously been applied to vacuum solutions in both General Relativity and…
What can abelian gauge theories teach us about kinematic algebras?
Kymani Armstrong-Williams, Silvia Nagy, Chris D. White +1
The phenomenon of BCJ duality implies that gauge theories possess an abstract kinematic algebra, mirroring the non-abelian Lie algebra underlying the colour information. Although t…
