Abstract

GRANDA, Luis Norberto. The Scalar Field Model of Dark Energy in the Framework of the Holographic Principle. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2020, vol.44, n.170, pp.133-141.  Epub June 14, 2021. ISSN 0370-3908.  https://doi.org/10.18257/raccefyn.966.

We study cosmological solutions for a scalar field minimally coupled to the curvature, in the framework of holographic dark energy. Phantom solutions can be obtained without introducing ghosts' degrees of freedom, and the autonomous system contains stable accelerated expansion solutions and de Sitter attractors. For the non-minimally coupled scalar field the special case of the conformal coupling is analyzed, and it is shown that dynamically evolving scalar field produces the effect of the cosmological constant.

Keywords : Dark Energy; Holographic Principle; Scalar Field.
