P. S. Ens, A. F. Santos

AI总结:

本研究采用源自黑洞分形表面的Barrow全息暗能量模型,对$f(R,T)$修正引力理论的重构过程展开探究,给出了哈勃视界、未来事件视界、Granda-Oliveros截断等多种红外截断下的数值结果,以探寻两类理论间的关联。

摘要:

本文研究了一种从暗能量模型重构修正引力模型的成熟方法,旨在探寻这些理论之间的关联。本研究聚焦于$f(R,T)$修正引力理论,其中$R$表示里奇标量,$T$表示能量-动量张量的迹。我们采用源自黑洞分形表面的Barrow全息暗能量模型,对重构过程展开研究。随后给出了针对多种红外截断的数值结果,例如哈勃视界、未来事件视界以及Granda-Oliveros截断。

英文摘要:

In this paper, we investigate one of the established methods for reconstructing modified gravity models from a dark energy model, with the aim of discovering relationships between these theories. In this study, we focus on the $f(R,T)$ modified gravity theory, where $R$ denotes the Ricci scalar and $T$ represents the trace of the energy-momentum tensor. We employ Barrow's holographic dark energy model, derived from fractal surfaces of black holes, to investigate the reconstruction process. The numerical results are subsequently presented for various infrared cutoffs, such as the Hubble horizon, future event horizon, and Granda-Oliveros cutoff.
