ModMax Electrodynamics and Holographic Magnetotransport
José Barrientos, Nicolás Cáceres, Felipe Diaz +1
We study magnetotransport in a holographic model where ModMax nonlinear electrodynamics is coupled to Einstein anti--de Sitter gravity. To incorporate momentum relaxation, we intro…
Gravitational instantons with conformally coupled scalar fields
José Barrientos, Adolfo Cisterna, Cristóbal Corral +1
We present novel regular Euclidean solutions to General Relativity in presence of Maxwell and conformally coupled scalar fields. In particular, we consider metrics of the Eguchi-Ha…
AdS-Taub-NUT spacetimes and exact black bounces with scalar hair
José Barrientos, Adolfo Cisterna, Nicolás Mora +1
We present a new family of exact four-dimensional Taub-NUT spacetimes in Einstein- theory supplemented with a conformally coupled scalar field exhibiting a power-counting super-…
Four-dimensional black holes with scalar hair in nonlinear electrodynamics
José O. Barrientos, P. A. González, Yerko Vásquez
We consider a gravitating system consisting of a scalar field minimally coupled to gravity with a self-interacting potential and a U(1) nonlinear electromagnetic field. Solving ana…
