Extrinsic Renormalization of New Massive Gravity
Cristóbal Corral, Rodrigo Olea, Leonardo Sanhueza
The renormalization of asymptotically AdS spacetimes in New Massive Gravity is studied using boundary terms constructed with the extrinsic curvature. For generic values of the theo…
corrections to self-dual gravitational instantons
José Luis V. Cerdeira, Cristóbal Corral, Tomás Ortín
We study the corrections to self-dual gravitational instantons in the context of the four-dimensional Cano--Ruipérez action, which can be obtained by the compactification of t…
Hadronic lensing
Fabrizio Canfora, Cristóbal Corral, Borja Diez
We introduce an analytic approach to study gravitational lensing in the presence of a distribution of hadrons. The situation is analogous to the propagation of photons in a medium…
Planar AdS multi-NUT spacetimes and Kaluza-Klein multi-monopoles
Cristóbal Corral, Cristián Erices, Daniel Flores-Alfonso +1
In higher-dimensional Einstein-AdS gravity, it is well known that planar and static anti-de Sitter black holes can be endowed with multiple rotation parameters via a large-gauge tr…
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…
Electric/magnetic duality of dyonic Kerr-Newman-NUT-AdS spacetimes
Cristóbal Corral, Rodrigo Olea
We study the (anti-)self-duality conditions under which the electric and magnetic parts of the conserved charges of the dyonic Kerr-Newman-NUT-AdS solution become equivalent. Withi…
Self-gravitating solutions in Yang-Mills-Chern-Simons theory coupled to 3D massive gravity
Cristóbal Corral, Daniel Flores-Alfonso, Gastón Giribet +1
We study self-gravitating solutions of 3-dimensional massive gravity coupled to Yang-Mills-Chern-Simons gauge theory. Among these, there is a family of asymptotically Warped-Anti d…
Asymptotically AdS black hole with a conformally-coupled scalar field in the first-order formalism of gravity
L. Avilés, C. Corral, F. Izaurieta +2
We present a novel asymptotically anti-de Sitter black hole solution with conformally-coupled scalar fields in the first-order formalism of gravity in four dimensions. To do so, we…
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…
Self duality in unconventional conformal supersymmetry
Pedro D. Alvarez, Cristóbal Corral, Jorge Zanelli
In this work, we study (anti-)self duality conditions in unconventional conformal supersymmetry. We focus on a theory constructed in a Townsend-MacDowell-Mansouri form for an $SU(2…
Gravitating anisotropic merons and squashed spheres in the three-dimensional Einstein-Yang-Mills-Chern-Simons theory
Fabrizio Canfora, Cristóbal Corral
We construct the first analytic examples of self-gravitating anisotropic merons in the Einstein-Yang-Mills-Chern-Simons theory in three dimensions. The gauge field configurations h…
