论文摘要

我们考虑$ f(r)$重力理论,该理论统一了$ r^n $通货膨胀和暗能量模型。首先,从宇宙微波背景的最终Planck数据中,我们获得了一个条件,$ 1.977 <n <2.003 $。接下来,在此约束下,我们研究了三个模型的局部重力测试。我们发现,即使在地球的曲率尺度上,$ r^n $术语也可以在黑暗的能量术语中占主导地位,这与直觉相反。但是,$ r^n $项不会放松或收紧三种型号的约束。

We consider $f(R)$ gravity theories which unify $R^n$ inflation and dark energy models. First, from the final Planck data of the cosmic microwave background, we obtain a condition, $1.977 < n < 2.003$. Next, under this constraint, we investigate local-gravity tests for three models. We find that the $R^n$ term can dominate over the dark energy term even at the Earth's curvature scale, contrary to intuition; however, the $R^n$ term does not relax or tighten the constraints on the three models.
