Statefinder Diagnostic for Phantom Model with $V(\phi)=V_{0}\exp(-\lambda{\phi}^2)$

Astrophysics 2009-11-16 v2

Abstract

We investigate the phantom field with potential V(ϕ)=V0exp(λϕ2)V(\phi)=V_{0}\exp(-\lambda{\phi}^2) and dark matter in the spatially flat FRW model. It has been shown by numerical calculation that there is a attractor solution in this model. We also apply the statefinder diagnostic to this phantom model. It is shown that the evolving trajectories of this scenario in the srs-r diagram is quite different form other dark energy models.
