Alternative formulations of the twistor double copy
Erick Chacón, Silvia Nagy, Chris D. White
The classical double copy relating exact solutions of biadjoint scalar, gauge and gravity theories continues to receive widespread attention. Recently, a derivation of the exact cl…
The double copy of the multipole expansion
Erick Chacón, Andres Luna, Chris D. White
We consider the classical double copy, that relates solutions of biadjoint scalar, gauge and gravity theories. Using a recently developed twistor expression of this idea, we use we…
The Weyl double copy from twistor space
Erick Chacón, Silvia Nagy, Chris D. White
The Weyl double copy is a procedure for relating exact solutions in biadjoint scalar, gauge and gravity theories, and relates fields in spacetime directly. Where this procedure com…
New heavenly double copies
Erick Chacón, Hugo García-Compeán, Andres Luna +2
The double copy relates scattering amplitudes and classical solutions in Yang-Mills theory, gravity, and related field theories. Previous work has shown that this has an explicit r…
Self-dual gravity via Hitchin's equations
Erick Chacon, Hugo Garcia-Compean
In this work half-flat metrics are obtained from Hitchin's equations. The SU Hitchin's equations are obtained and as a consequence of them, the Husain-Park equation is fo…
The self-dual classical double copy, and the Eguchi-Hanson instanton
David S. Berman, Erick Chacón, Andrés Luna +1
The double copy is a map from non-abelian gauge theories to gravity, that has been demonstrated both for scattering amplitudes and exact classical solutions. In this study, we reco…
Mapping food insecurity in the Brazilian Amazon using a spatial item factor analysis model
Erick A. Chacón-Montalván, Luke Parry, Emanuele Giorgi +4
Food insecurity, a latent construct defined as the lack of consistent access to sufficient and nutritious food, is a pressing global issue with serious health and social justice im…
