Renormalization of Einstein-Gauss-Bonnet AdS gravity
Giorgos Anastasiou, Ignacio J. Araya, Avik Chakraborty +2
The asymptotic analysis for the metric of a generic solution of Einstein-Gauss-Bonnet AdS theory is provided by solving the field equations in the Fefferman-Graham frame. Using sta…
Self-dual instantons and gravitating dyons in non-Abelian ModMax theory
Fabrizio Canfora, Cristóbal Corral, Borja Diez +2
Motivated by the recent interest in conformal and duality invariant nonlinear electrodynamics, we study the non-Abelian extension of ModMax electrodynamics. The theory is parameter…
Nonconformally Ricci-flat instantons in Conformal Gravity with and without nonlinear matter fields
Cristóbal Corral, Borja Diez, Eleftherios Papantonopoulos
In this work, we study nonconformally Ricci-flat gravitational instantons in four-dimensional Conformal Gravity, both in vacuum and in the presence of nonlinear conformal matter. F…
Inhomogeneous metrics on complex bundles in Lovelock gravity
Cristóbal Corral, Borja Diez, Daniel Flores-Alfonso +2
We consider Lovelock gravity in arbitrary, even dimensions. We find a large class of new gravitational instantons by considering extended nontrivial circle bundles over Kähler mani…
Euclidean AdS wormholes and gravitational instantons in the Einstein-Skyrme theory
Fabrizio Canfora, Cristóbal Corral, Borja Diez
Euclidean AdS wormholes provide a natural setup for studying the AdS/CFT correspondence with multiple boundaries. However, from a bottom-up perspective, they cannot be embedded in…
