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…
Inflation, dark matter and dark energy in the string landscape
Andrew R Liddle, L Arturo Ureña-López
We consider the conditions needed to unify the description of dark matter, dark energy and inflation in the context of the string landscape. We find that incomplete decay of the in…
Gravitational cooling of self-gravitating Bose-Condensates
F. Siddhartha Guzman, L. Arturo Urena-Lopez
Equilibrium configurations for a self-gravitating scalar field with self-interaction are constructed. The corresponding Schrödinger-Poisson (SP) system is solved using finite diffe…
Scalar phantom energy as a cosmological dynamical system
L. Arturo Urena-Lopez
Phantom energy can be visualized as a scalar field with a (non-canonical) negative kinetic energy term. We use the dynamical system formalism to study the attractor behavior of a c…
On the nature of dark matter
T. Matos, L. A. Urena-Lopez
Dark matter in the universe seems to be one of the most important puzzles science has to face in this moment. In this essay we point out that dark matter could be a spin-0 fundamen…
Newtonian Collapse of Scalar Field Dark Matter
F. Siddhartha Guzman, L. Arturo Urena-Lopez
In this letter, we develop a Newtonian approach to the collapse of galaxy fluctuations of scalar field dark matter under initial conditions inferred from simple assumptions. The fu…
