论文摘要
在本文中，使用手推车熵，我们提出了一种相互作用的手感全息暗能量（BHDE）的模型。特别是，我们研究了一个空间扁平的FLRW宇宙的演变，该宇宙由无压的暗物质和BHDE组成，该宇宙通过良好动机的相互作用项相互相互作用。将哈勃视野视为IR截断，然后我们研究重要的宇宙学参数的进化历史，尤其是密度参数，状态参数方程以及BHDE模型中的减速参数，并在模型中找到令人满意的行为。我们通过研究场方程的渐近行为来对场方程的动力学进行详细的研究，而我们通过使用lourent系列来编写尺度因子的分析表达式。最后，我们研究了引力热力学在相互作用的BHDE模型中与动态明显视野作为宇宙学边界的含义。特别是，我们通过假设明显的视野赋予鹰温度和手推车熵来研究广义第二定律的生存能力。
In this paper, using Barrow entropy, we propose an interacting model of Barrow holographic dark energy (BHDE). In particular, we study the evolution of a spatially flat FLRW universe composed of pressureless dark matter and BHDE that interact with each other through a well-motivated interaction term. Considering the Hubble horizon as the IR cut-off, we then study the evolutionary history of important cosmological parameters, particularly, the density parameter, the equation of state parameter, and the deceleration parameter in the BHDE model and find satisfactory behaviors in the model. We perform a detailed study on the dynamics of the field equations by studying the asymptotic behavior of the field equations, while we write the analytic expression for the scale factor with the use of Laurent series. Finally, we study the implications of gravitational thermodynamics in the interacting BHDE model with the dynamical apparent horizon as the cosmological boundary. In particular, we study the viability of the generalized second law by assuming that the apparent horizon is endowed with Hawking temperature and Barrow entropy.
