Towards a de Sitter quintom-like cosmology from a reduction of a 7-dimensional theory
Ricardo Escobedo, Roberto Santos-Silva, Claudia Moreno +1
In this article, we analyze a 7-dimensional theory that, upon dimensional reduction, transforms into an effective 4-dimensional action in which a generic metric is involved. A…
Some inflationary models under the light of Planck 2018 results
Daniel Pozo, Jordan Zambrano, Ismael Villegas +2
In this work we study four well-known inflationary scenarios that are reported by the most recent Planck observations: Natural inflation, Hilltop quartic inflation, Starobinsky inf…
Post-Newtonian Gravitational Waves with cosmological constant from the Einstein-Hilbert theory
Ricardo Escobedo, Claudia Moreno, Rafael Hernández-Jiménez
We study the Post-Newtonian approach implemented to the Einstein-Hilbert action adding the cosmological constant at 1PN order. We consider very small values of to derive th…
Geometrical scalar back-reaction effects in inflation
Rafael Hernández-Jiménez, Claudia Moreno
Starting with the Lagrangian formulation of General Relativity, we will conduct an investigation into the production of spacetime waves, due to a geometric boundary term of a close…
