变引力常量的全息暗能量

Holographic dark energy with varying gravitational constant

Mubasher Jamil, Emmanuel N. Saridakis, M. R. Setare

摘要:

我们研究了具有不同引力常量的全息暗能量场景,在平坦和非平坦背景几何中。我们提取的精确微分方程确定的暗能量密度参数的演变,其中包括$G$ -变化校正条款。进行低红移展开的暗能量状态方程,我们提供了所涉及的参数的函数的电流密度参数,全息暗能量常数和$G$ -变化。

英文摘要:

We investigate the holographic dark energy scenario with a varying gravitational constant, in flat and non-flat background geometry. We extract the exact differential equations determining the evolution of the dark energy density-parameter, which include $G$-variation correction terms. Performing a low-redshift expansion of the dark energy equation of state, we provide the involved parameters as functions of the current density parameters, of the holographic dark energy constant and of the $G$-variation.
