Interacting holographic dark energy in the scalar-Gauss-Bonnet gravity

Abstract

In this paper we study cosmological application of interacting holographic dark energy density in the scalar-Gauss-Bonnet framework. We employ the interacting holographic model of dark energy to obtain the equation of state for the interacting holographic energy density in spatially flat universe. Our calculation show, taking ${\Omega }_{\Lambda }=0.73$ for the present time, it is possible to have $w_{\mathrm{\Lambda }}^{eff}$ crossing -1. This implies that one can generate phantom-like equation of state from the interacting holographic dark energy model in flat universe in the scalar-Gauss-Bonnet cosmology framework. Then we reconstruct the potential of the scalar field.
