论文摘要

在这项工作中,我们提出了一种使用Barrow熵在空间平坦的FLRW宇宙中的Barrow全息暗能量(BHDE)的非相互作用模型,考虑到IR截止值为Hu​​bble Horizo​​n。我们研究了重要的宇宙学参数的进化历史,尤其是EOS $(ω_{B})$,减速参数以及BHDE和物质密度参数,并且还观察到模型BHDE中的令人满意的行为。此外,为了描述宇宙的加速膨胀,BHDE模型与典型标量场的对应关系已重建。

In this work, we propose a non-interacting model of Barrow holographic dark energy (BHDE) using Barrow entropy in a spatially flat FLRW Universe considering the IR cutoff as the Hubble horizon. We study the evolutionary history of important cosmological parameters, in particular, EoS $(ω_{B})$, deceleration parameter and, the BHDE and matter density parameter and also observe satisfactory behaviours in the BHDE the model. In addition, to describe the accelerated expansion of the Universe the correspondence of the BHDE model with the quintessence scalar field has been reconstructed.
