$f(R)$引力和Tsallis全息暗能量

$f(R)$ gravity and Tsallis holographic dark energy

P. S. Ens, A. F. Santos

摘要:

考虑了$f(R)$引力理论。这是一个推广爱因斯坦-希尔伯特作用量的引力理论。在此背景下,全息暗能量模型进行了研究。基于全息原理,利用Tsallis非广延熵引入了暗能量密度。然后研究了该模型的Friedmann方程、减速参数和状态方程。

英文摘要:

The $f(R)$ gravity theory is considered. It is a gravitational theory that generalizes the Einstein-Hilbert action. In this context, a holographic dark energy model is studied. Tsallis non-extensive entropy is used to introduce the dark energy density based on the holographic principle. Then the Friedmann equation, deceleration parameter, and equation of state for this model are investigated.
