Smooth Crossing of Line in a Single Scalar Field Model

Figure 2

The tracking behaviour of the scalar field is demonstrated. Thick and the thin lines correspond to and , respectively. The crossing of the phantom divide line occurs at the minima and local maxima (where overtakes ) of the dark energy density. Dashed line corresponds to in the absence of background matter. The dark energy is found to remain subdominant till the second crossing.
