统一全息暴胀与全息暗能量:协变方法

Unifying Holographic Inflation with Holographic Dark Energy: a Covariant Approach

Shinichi Nojiri, S. D. Odintsov, V. K. Oikonomou, Tanmoy Paul

摘要:

在本文中,我们使用全息方法来描述我们的宇宙的早期加速和晚期加速时代的统一方式。这种“全息统一”被发现与各种有或没有物质场的高曲率宇宙学模型有对应关系。相应的全息截止值是根据粒子视界及其导数,或未来视界及其导数确定的。因此,我们提出的全息能量密度能够从全息的角度融合宇宙的各种宇宙学时代。我们发现全息对应的几个$F(R)$重力模型,包括轴子- $F(R)$重力模型,几个高斯-邦尼$F(G)$模型,最后的$F(T)$模型,并在每种情况下,我们表明,它是可能的描述在同一全息模型的背景下,在一个统一的方式通货膨胀和后期加速。

英文摘要:

In the present paper, we use the holographic approach to describe the early-time acceleration and the late-time acceleration eras of our Universe in a unified manner. Such ``holographic unification'' is found to have a correspondence with various higher curvature cosmological models with or without matter fields. The corresponding holographic cut-offs are determined in terms of the particle horizon and its derivatives, or the future horizon and its derivatives. As a result, the holographic energy density we propose is able to merge various cosmological epochs of the Universe from a holographic point of view. We find the holographic correspondence of several $F(R)$ gravity models, including axion-$F(R)$ gravity models, of several Gauss-Bonnet $F(G)$ models and finally of $F(T)$ models, and in each case we demonstrate that it is possible to describe in a unified way inflation and late-time acceleration in the context of the same holographic model.
