Reconstructing a String-Inspired Quintom Model of Dark Energy
Abstract
Description
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.
