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…
