Born-Infeld Gravity: Constraints from Light-by-Light Scattering and an Effective Field Theory Perspective
Jose Beltrán Jiménez, Adrià Delhom, Gonzalo J. Olmo +1
By using a novel technique that establishes a correspondence between general relativity and metric-affine theories based on the Ricci tensor, we are able to set stringent constrain…
Anisotropic deformations in a class of projectively-invariant metric-affine theories of gravity
Jose Beltrán Jiménez, Daniel de Andrés, Adrià Delhom
Among the general class of metric-affine theories of gravity, there is a special class conformed by those endowed with a projective symmetry. Perhaps the simplest manner to realise…
On cosmological signatures of baryons-dark energy elastic couplings
Jose Beltrán Jiménez, Dario Bettoni, David Figueruelo +1
We consider a scenario where dark energy and baryons are dynamically coupled without any energy transfer. In this scenario, the background cosmology is unaffected and, at the pertu…
Minkowski space in gravity
Jose Beltran Jimenez, Alexey Golovnev, Tomi Koivisto +1
The full set of solutions of gravity with the Minkowski metric is considered in this note. At the 4-th order in perturbations around the trivial tetrad solution, a new mode…
Probing cosmological fields with gravitational wave oscillations
Jose Beltrán Jiménez, Jose María Ezquiaga, Lavinia Heisenberg
Gravitational wave (GW) oscillations occur whenever there are additional tensor modes interacting with the perturbations of the metric coupled to matter. These extra modes can aris…
Revisiting the Stability of Quadratic Poincaré Gauge Gravity
Jose Beltrán Jiménez, Francisco José Maldonado Torralba
Poincaré gauge theories provide an approach to gravity based on the gauging of the Poincaré group, whose homogeneous part generates curvature while the translational sector gives r…
