单标量场模型中$w_Λ = -1$线的光滑交叉

Smooth crossing of $w_Λ = -1$ line in a single scalar field model

A. K. Sanyal

摘要:

在背景冷暗物质存在的情况下,对于最简单形式的广义k-本质宇宙学模型,在单个最小耦合标量场下,幻影分界线$w_Λ=-1$的平滑双交叉是可能的.这样的交叉是足够晚的时间瞬态现象,并且不具有任何病理行为。

英文摘要:

Smooth double crossing of the phantom divide line $w_Λ=-1$ has been found possible with a single minimally coupled scalar field for the most simple form of generalized k-essence cosmological model, in the presence of background cold dark matter. Such crossing is a sufficiently late time transient phenomena and does not have any pathological behaviour.
