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…

Holographic renormalization of Horndeski gravity
Nicolás Cáceres, Cristóbal Corral, Felipe Diaz +1
We study the renormalization of a particular sector of Horndeski theory. In particular, we focus on the nonminimal coupling of a scalar field to the Gauss-Bonnet term and its kinet…

Quadratic gravity and conformally coupled scalar fields
Nicolas Caceres, Jose Figueroa, Julio Oliva +2
We construct black hole solutions in four-dimensional quadratic gravity, supported by a scalar field conformally coupled to quadratic terms in the curvature. The conformal matter L…
