Holographic Dark Energy Model and Scalar-Tensor Theories
arXiv:0808.1424 · doi:10.1007/s10714-008-0676-7
Abstract
We study the holographic dark energy model in a generalized scalar tensor theory. In a universe filled with cold dark matter and dark energy, the effect of potential of the scalar field is investigated in the equation of state parameter. We show that for a various types of potentials, the equation of state parameter is negative and transition from deceleration to acceleration expansion of the universe is possible.
