Quintessence and Phantom Based On Dilaton

Based on dilatonic dark energy model, we consider two cases: dilaton field with positive kinetic energy(coupled quintessence) and with negative kinetic energy(phantom). In the two cases, we investigate the existence of attractor solutions which correspond to an equation of state parameter ω = −1 and a cosmic density parameter Ωσ = 1. We find that the… CONTINUE READING
