Riemannian and teleparallel descriptions of the scalar field gravitational interaction
(1998-02-01)
A comparative study between the metric and the teleparallel descriptions of gravitation is made for the case of a scalar field. In contrast to the current belief that only spin matter could detect the teleparallel geometry, ...

Cosmological constraints on scalar field dark matter
(2021-01-01)
This paper aims to put constraints on the parameters of the Scalar Field Dark Matter (SFDM) model, when dark matter is described by a free real scalar field filling the whole universe, plus a cosmological constant term. ...
Exact solutions for the fluctuations in flat FRW universe coupled to a scalar fields
(Springer/plenum Publishers, 2006-12)
Some exact solutions for the small-first-order perturbations of an FRW metric minimally coupled to a neutral massive scalar field are presented.
Decaying vacuum cosmology and its scalar field description
(IOP Publishing LtdBristol, 2014)
We discuss the cosmological consequences of an interacting model in the dark
sector in which the component evolves as a truncated power series of the
Hubble parameter. We also discuss some of the thermodynamic features ...
Propagation of Scalar Fields in a Plane Symmetric Spacetime
(2016-12-01)
The present article deals with solutions for a minimally coupled scalar field propagating in a static plane symmetric spacetime. The considered metric describes the curvature outside a massive infinity plate and exhibits ...
