A single scalar field model of dark energy with equation of state crossing −1

Year: 2005

Type: article

Abstract: In this paper we study the possibility of building models of dark energy with equation of state across −1 and propose explicitly a model with a single scalar field which gives rise to an equation of state larger than −1 in the past and less than −1 at the present time, consistent with the current observations.
