Towards a Non-Perturbative Classical Double Copy
Kymani Armstrong-Williams
We construct an exact solution-generating correspondence between restricted ansatz sectors of quartic biadjoint scalar theory, complexified Yang--Mills theory and four-dime…
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…
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…
Machine Learning Mutation-Acyclicity of Quivers
Kymani T. K. Armstrong-Williams, Edward Hirst, Blake Jackson +1
Machine learning (ML) has emerged as a powerful tool in mathematical research in recent years. This paper applies ML techniques to the study of quivers -- a type of directed multig…
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…
A spinorial double copy for supergravity
Kymani Armstrong-Williams, Chris D. White
The Weyl double copy is a formula relating solutions of scalar, gauge and gravity theories, and is related to the BCJ double copy for scattering amplitudes. The latter relates Yang…
Non-perturbative aspects of the self-dual double copy
Kymani Armstrong-Williams, Chris D. White, Sam Wikeley
The double copy is by now a firmly-established correspondence between amplitudes and classical solutions in biadjoint scalar, gauge and gravity theories. To date, no strongly coupl…
