Contribution
It introduces a novel dilatonic framework for holographic dark energy, connecting scalar field energy density with holographic principles in a flat universe.
Findings
Model can describe observed accelerated expansion with c ≥ 1
Reconstructed kinetic term and scalar field dynamics
Provides a new link between holography and scalar field models
Abstract
We present a dilatonic description of the holographic dark energy by connecting the holographic dark energy density with the dilaton scalar field energy density in a flat Friedmann-Robertson-Walker universe. We show that this model can describe the observed accelerated expansion of our universe with the choice and reconstruct the kinetic term as well as the dynamics of the dilaton scalar field.
