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…
Gravitational Memory Beyond Null Infinity through Finite-Distance Carrollian Screens
Felipe Diaz, Sercan Hüsnügil, Oriana Labrin +1
We investigate gravitational memory beyond null infinity by studying finite-distance null hypersurfaces endowed with Carrollian geometry. We show that the intrinsic degenerate geom…
Self-gravitating baryonic tubes supported by - and -mesons and its flat limit
Gonzalo Barriga, Carla Henríquez-Baez, Leonardo Sanhueza +1
In this paper, we construct self-gravitating topological solitons in the Einstein non-linear sigma model coupled to -vector mesons in four space-time dimensions. These s…
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…
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…
Hairy Taub-NUT/Bolt-AdS solutions in Horndeski theory
Esteban Arratia, Cristobal Corral, Jose Figueroa +1
We present different Taub-NUT/Bolt-anti de Sitter (AdS) solutions in a shift-symmetric sector of Horndeski theory of gravity possessing nonminimal kinetic coupling of scalar fields…
