3d Lovelock gravity and the holographic c-theorem: Proof at all orders and resummation
Gokhan Alkac, Luis Guajardo, Hikmet Ozsahin
We prove that 3d Lovelock gravity, the Horndeski theory obtained from the regularized Lovelock invariants in three dimensions, admits a holographic c-theorem at all orders and for…
Black holes and phase transitions in Conformal Gravity
Luis Guajardo, Luis Gutiérrez Frez, Seyed Naseh Sajadi +1
We explore the thermodynamic properties of static black holes in conformal gravities in arbitrary, even dimensions. In the spherically symmetric case, up to local Weyl rescalings,…
Merons beyond Yang-Mills theory
Borja Diez, Luis Guajardo
Within the wide variety of topological solitons supported by Yang--Mills theory, merons occupy a particularly distinguished role. Despite their simplicity, they represent genuinely…
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…
Transport coefficients of charged Gauss-Bonnet black holes with arbitrary topology
Moisés Bravo-Gaete, Luis Guajardo, Daniel F. Higuita-Borja +1
In this study, we present a novel family of exact black hole solutions constructed in the context of five-dimensional Gauss-Bonnet gravity. These solutions add a non-linear charge…
Primary scalar hair in Gauss-Bonnet black holes with Thurston horizons
Luis Guajardo, Julio Oliva
In this work, we construct novel asymptotically locally AdS black hole solutions of Einstein-Gauss-Bonnet theory at the Chern-Simons point, supported by a scalar field that gen…
Microscopic entropy of static black holes in 3d Lovelock gravities
Gokhan Alkac, Luis Guajardo, Hikmet Ozsahin
We give a microscopic derivation of the semi-classical entropy of static black holes in 3d Lovelock gravities, which are certain 3d Horndeski theories that were recently discovered…
Black string spectrum of shift-symmetric Horndeski theories
Luis Guajardo
In the present work, we study four-dimensional black strings in Horndeski models with translation invariance. Imposing that the scalar field depends on the string-generator coordin…
Exploring the shear viscosity in four-dimensional planar black holes beyond General Relativity
Moisés Bravo-Gaete, Luis Guajardo, Fabiano F. Santos
The well known shear viscosity to entropy density ratio () cannot be computed when the black hole space-time has zero thermodynamic entropy. This is the case, for example, whe…
Non-linear charged planar black holes in four-dimensional Scalar-Gauss-Bonnet theories
Moisés Bravo-Gaete, Luis Guajardo, Julio Oliva
In this work, we consider the recently proposed well-defined theory that permits a healthy limit of the Einstein-Gauss-Bonnet combination, which requires the addition of a…
Axionic charged black branes with arbitrary scalar nonminimal coupling
Adolfo Cisterna, Luis Guajardo, Mokhtar Hassaine
In this paper, we construct four-dimensional charged black branes of a nonminimally coupled and self-interacting scalar field. In addition to the scalar and Maxwell fields, the mod…
Quintic quasi-topological gravity
Adolfo Cisterna, Luis Guajardo, Mokhtar Hassaine +1
We construct a quintic quasi-topological gravity in five dimensions, i.e. a theory with a Lagrangian containing terms and whose field equations are of second order…
A Cardy-like formula for rotating black holes with planar horizon
Moisés Bravo Gaete, Luis Guajardo, Mokhtar Hassaïne
We show that the semiclassical entropy of -dimensional rotating (an)isotropic black holes with planar horizon can be successfully computed according to a Cardy-like formula. Thi…
