重建一个基于弦的暗能量Quintom模型
Reconstructing a String-Inspired Quintom Model of Dark Energy
摘要：
本文提出了一种用蔡等人给出的拉格朗日量$ {\cal L} = -V (ϕ) \sqrt{1 - α' {\nabla}_μ ϕ\nabla^μ ϕ+ β' ϕ\Box ϕ} $重建弦激发的暗能量模型的简单方法。例如，这可以允许状态方程参数越过宇宙学常数边界$ (w=-1) $。我们根据动力学暗能量的三种参数化形式重建了这个模型。
英文摘要：
In this paper, we develop a simple method for the reconstruction of the string-inspired dark energy model with the lagrangian $ {\cal L} = -V (ϕ) \sqrt{1 - α' {\nabla}_μ ϕ\nabla^μ ϕ+ β' ϕ\Box ϕ} $ given by Cai et. al., which may allow the equation-of-state parameter cross the cosmological constant boundary $ (w=-1) $. We reconstruct this model in the light of three forms of parametrization for dynamical dark energy.
