In this work, we propose a new dark energy (DE) model by applying the Barrow entropy and the holographic principle, with a time scale as IR cut-off. Analyzing the conformal time as well as universe’s age as infrared cut-offs, we explore the cosmological importance of the suggested DE models and examine the universe evolution filled with the proposed DE applicants and a pressure-less matter. We observe that the equation of state, deceleration, the density parameters can present adequate nature, and these models may also explain the late-time acceleration though the proposed models are unstable except for some values of Barrow exponent Δ. Furthermore, we mention the consequences of the presence of interaction among the universe sectors.

巴罗年代学暗能量

在这项工作中，我们通过应用巴罗熵和全息原理提出了一种新的暗能量 (DE) 模型，其时间尺度为 IR 截止。通过分析共形时间和宇宙年龄作为红外截止值，我们探索了建议的 DE 模型的宇宙学重要性，并检查了充满建议的 DE 申请者和无压物质的宇宙演化。我们观察到状态方程、减速度、密度参数可以表现出足够的性质，这些模型也可以解释后期加速度，尽管除了一些 Barrow 指数值之外，所提出的模型是不稳定的Δ. 此外，我们提到了宇宙扇区之间存在相互作用的后果。
