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…
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…
Non-Abelian black holes in conformal gravity
Daniel Flores-Alfonso
The first black hole solutions of the SU(N) Bach-Yang-Mills equations are presented. Static generalizations breaking spherical symmetry are also constructed. These constitute the f…
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…
Nonlinearly charging the conformally dressed black holes preserving duality and conformal invariance
Eloy Ayón-Beato, Daniel Flores-Alfonso, Mokhtar Hassaine
We start this paper by concisely rederiving ModMax, which is nothing but the unique nonlinear extension of Maxwell's equations preserving conformal and duality invariance. The meri…
Axial anomaly in nonlinear conformal electrodynamics
Francisco Colipí-Marchant, Cristóbal Corral, Daniel Flores-Alfonso +1
We study the axial anomaly of Dirac spinors on gravitational instanton backgrounds in the context of nonlinear electrodynamics. In order to do so, we consider Einstein gravity mini…
Higher-curvature generalization of Eguchi-Hanson spaces
Cristóbal Corral, Daniel Flores-Alfonso, Gastón Giribet +1
We construct higher-dimensional generalizations of the Eguchi-Hanson gravitational instanton in the presence of higher-curvature deformations of general relativity. These spaces ar…
Analytic non-homogeneous condensates in the -dimensional Yang-Mills-Higgs-Chern-Simons theory at finite density
Fabrizio Canfora, Daniel Flores-Alfonso, Marcela Lagos +1
We construct the first analytic examples of non-homogeneous condensates in the Georgi-Glashow model at finite density in dimensions. The non-homogeneous condensates, which…
Phase transitions of black strings in dynamical Chern-Simons modified gravity
Cristóbal Corral, Cristián Erices, Daniel Flores-Alfonso +1
We study conserved charges and thermodynamics of analytic rotating anti-de Sitter black holes with extended horizon topology -- also known as black strings -- in dynamical Chern-Si…
Chern Index of Taub-Bolt instantons in Einstein-Born-Infeld gravity
Daniel Flores-Alfonso, Hernando Quevedo
Partition functions can be calculated by saddle point approximations whenever regular solutions exist, as they dominate the path integral. We examine a regular Taub-Bolt dyon of Ei…
Topological Characterization of Higher Dimensional Charged Taub-NUT Instantons
Daniel Flores-Alfonso, Hernando Quevedo
Recently, we have shown that non-selfdual self-gravitating dyonic fields with magnetic mass generalize the Dirac monopole. The unique topological index, which characterizes the fie…
Flux quantization in dilatonic Taub-NUT dyons
Daniel Flores-Alfonso, Hernando Quevedo
Spacetimes that include a boundary at infinity have a non-trivial topology. The homology of the background influences gauge fields living on them and lead to topological charges. W…
