Lovelock type brane cosmology
Amairani Arroyo, Rubén Cordero, Giovany Cruz +1
The cosmological implications of the geodetic brane gravity model, enhanced by geometrical terms of Gibbons-Hawking-York (GHY) type and Gibbons-Hawking-York-Myers type (GHYM), care…
General perturbations in D+1 standard and brane cosmology revisited
Zoé Delfín, Rubén Cordero, Tonatiuh Matos +1
In the present work, we generalize the theory of perturbations in a D + 1 dimensional space-time with cosmological constant, studying scalar, vector and tensor perturbations, as we…
European Spallation Source as a searching tool for an ultralight scalar field
Rubén Cordero, Luis A. Delgadillo, O. G. Miranda
Dark matter (DM) nature is one of the major issues in physics. The search for a DM candidate has motivated the known proposal of an ultralight scalar field (ULSF). We explore the p…
Perturbations and stability conditions of k-essence and kinetic gravity braiding models in two-field measure theory
Ruben Cordero, Josue De-Santiago, Omar G. Miranda +1
We study cosmological perturbations for k-essence and kinetic gravity braiding models in the context of the two-field measure theory (TMT). Considering scalar perturbations and the…
Cosmological restrictions for two DGP branes in a bulk with compactified extra dimension
Jairo Capilla-Valdepeña, Rubén Cordero, Felipe Maya-Ordóñez
We investigate the cosmological consequences of a two brane system embedded in a higher dimensional background spacetime with a compactified extra dimension described with an actio…
New Exact Supersymmetric Wave Functions for a Massless Scalar Field and Axion-Dilaton String Cosmology in a FRWL Metric
Ruben Cordero, Roberto D. Mota
We study the quantum cosmology of the 2D Hawking-Page massless scalar-field model and the homogeneous and isotropic dilation-axion string cosmology.For both models we find new exac…
