Four-dimensional Brane-Chern-Simons Gravity and Cosmology
F. Gómez, S. Lepe, P. Salgado
From the field equations corresponding to a 4-dimensional brane embedded in the 5-dimensional spacetime of the Einstein-Chern-Simons theory for gravity, we find cosmological soluti…
Brane gravity in 4D from Chern-Simons gravity theory
R. Díaz, F. Gómez, M. Pinilla +1
We evaluate a 5-dimensional Randall Sundrum type metric in the Lagrangian of the Einstein-Chern-Simons gravity, and then we derive an action and its corresponding field equations,…
Magnetic field generation from primordial black hole distributions
Ignacio J. Araya, Marcelo E. Rubio, Marco San Martin +4
We introduce a statistical method for estimating magnetic field fluctuations generated from primordial black hole (PBH) populations. To that end, we consider monochromatic and exte…
Most general theory of 3d gravity: Covariant phase space, dual diffeomorphisms, and more
Marc Geiller, Christophe Goeller, Nelson Merino
We show that the phase space of three-dimensional gravity contains two layers of dualities: between diffeomorphisms and a notion of "dual diffeomorphisms" on the one hand, and betw…
Topological Terms and the Misner String Entropy
Luca Ciambelli, Cristóbal Corral, José Figueroa +2
The method of topological renormalization in anti-de Sitter (AdS) gravity consists in adding to the action a topological term which renders it finite, defining at the same time a w…
First-order Lagrangian and Hamiltonian of Lovelock gravity
Pablo Guilleminot, Félix-Louis Julié, Nelson Merino +1
Based on the insight gained by many authors over the years on the structure of the Einstein-Hilbert, Gauss-Bonnet and Lovelock gravity Lagrangians, we show how to derive -- in an e…
