Dynamics of interacting dark energy
Gabriela Caldera-Cabral, Roy Maartens, L. Arturo Urena-Lopez
Dark energy and dark matter are only indirectly measured via their gravitational effects. It is possible that there is an exchange of energy within the dark sector, and this offers…
Triple unification of inflation, dark matter, and dark energy using a single field
Andrew R. Liddle, Cédric Pahud, L. Arturo Ureña-López
We construct an explicit scenario whereby the same material driving inflation in the early Universe can comprise dark matter in the present Universe, using a simple quadratic poten…
On the dynamics of a quadratic scalar field potential
L. Arturo Urena-Lopez, Mayra J. Reyes-Ibarra
We review the attractor properties of the simplest chaotic model of inflation, in which a minimally coupled scalar field is endowed with a quadratic scalar potential. The equations…
Unveiling the dynamics of the universe
L. Arturo Ureña--López
We present two methods for describing, from a pedagogical point of view, the solutions of Einstein's equations applied to a homogeneous and isotropic universe. In the first method,…
Complex Hybrid Inflation and Baryogenesis
David Delepine, Carlos Martinez, L. Arturo Urena-Lopez
We propose a hybrid inflation model with a complex waterfall field which contains an interaction term that breaks the U(1) global symmetry associated to the waterfall field charge.…
