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…
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…
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…
Curvaton reheating: an application to braneworld inflation
Andrew R. Liddle, L. Arturo Urena-Lopez
The curvaton was introduced recently as a distinct inflationary mechanism for generating adiabatic density perturbations. Implicit in that scenario is that the curvaton offers a ne…
Scalar Field Dark Matter and Galaxy Formation
Miguel Alcubierre, F. Siddhartha Guzman, Tonatiuh Matos +3
We present a general description of the scalar field dark matter (SFDM) hypothesis in the cosmological context. The scenario of structure formation under such a hypothesis is based…
