AI总结:

本文基于反德西特黑洞熵的全息暗能量模型,以哈勃视界为红外截断研究全息与慢滚暴胀,发现$n=1/3$和$n=1/2$的混沌势慢滚暴胀符合普朗克结果,小$b²$时模型可替代$Λ$CDM。

摘要:

基于反德西特黑洞的熵,已有研究提出了一种新的全息暗能量模型。当选择哈勃视界和粒子视界作为红外截断时,可实现宇宙的晚期加速膨胀。本文选取哈勃视界作为红外截断,在该模型中研究全息暴胀与慢滚暴胀。研究发现,对于混沌势$V_{0}ϕ^{n}$的慢滚暴胀,在$n=1/3$和$n=1/2$等特殊情况下与普朗克(Planck)结果相符,而全息暴胀则不被普朗克结果支持。随后,我们分析了该模型中的 reheating 温度和 reheating e 折叠数,发现结果支持$n=1/3$和$n=1/2$的情况。最后,我们利用动力学分析方法、状态探测器诊断对及哈勃图对该模型进行分析,结果表明当$b^{2}$取小值时,该模型无法与标准$Λ$CDM模型区分,可作为其替代模型。

英文摘要:

Based on the entropy of anti-de Sitter black hole, a new holographic dark energy model has been proposed. When the Hubble horizon and particle horizon are chosen as the IR cutoff, the late-time accelerated expansion of universe is realized. In this paper, we consider the Hubble horizon as the IR cutoff to investigate holographic inflation and slow-roll inflation in this model. We find that slow-roll inflation with the chaotic potential $V_{0}ϕ^{n}$ is favored by Planck results for some special cases, such as $n=1/3$ and $n=1/2$, while holographic inflation is not supported by Planck results. Then, we analyze the reheating temperature and the number of reheating e-folds in this model, and we find that the results favor the cases $n=1/3$ and $n=1/2$. Finally, we use the dynamical analysis method, statefinder diagnostic pairs, and the Hubble diagram to analyze this model. Our results indicate that when $b^{2}$ takes a small value, this model cannot be distinguished from the standard $Λ$CDM model and can serve as an alternative to it.
