论文摘要
我们通过包含标量场电位（即$ v（ϕ）$）来探索模拟重力公式。但是，我们没有考虑本学期的任何{\ it先验}特定表格。通过流体的参数状态的Chevallier-Polarski限制参数化，我们可以根据宇宙的红移来构建这种潜力的明确函数，并在模拟重力方法中获得分析溶液。我们修改了这些结果的一些宇宙学含义，此外，我们对潜在的$ v $进行了数值重建，这是模拟标量字段$ ϕ $的函数。
We explore the mimetic gravity formulation with the inclusion of a scalar field potential namely, $V(ϕ)$. However, we are not considering any {\it a priori} specific form this term. By means of the Chevallier-Polarski-Linder parametrization for the parameter state of the fluid we can construct an explicit function for such potential in terms of the cosmological redshift and obtain analytical solutions in the mimetic gravity approach. We revise some cosmological implications of these results and additionally we perform a numerical reconstruction for the potential $V$ as a function of the mimetic scalar field, $ϕ$.
