论文摘要
我们构建了Barrow全息暗能量（BHDE）的广义相互作用模型，红外截止型由哈勃地平线给出。我们分析了一个扁平的Friedmann-Lema-Robertson-Walker宇宙的宇宙演化，该宇宙被无压的暗物质，BHDE和辐射流体填充。假定宇宙的黑暗部门之间的相互作用是非重大起源，并满足了热力学的第二定律和le chatelier-braun原理。我们研究各种模型参数的行为，例如BHDE密度参数，状态参数方程，减速参数，混蛋参数和声速的平方。我们表明，我们的模型令人满意地检索了宇宙的热历史，并且与当前对某些参数值的观察结果一致，从而提供了描述暗能量的符合条件的候选者。我们最终探索了框架的热力学，特别关注了广义第二定律的有效性。
We construct a generalized interacting model of Barrow Holographic Dark Energy (BHDE) with infrared cutoff being given by the Hubble horizon. We analyze the cosmological evolution of a flat Friedmann-Lemaître-Robertson-Walker Universe filled by pressureless dark matter, BHDE and radiation fluid. The interaction between the dark sectors of the cosmos is assumed of non-gravitational origin and satisfying the second law of thermodynamics and Le Chatelier-Braun principle. We study the behavior of various model parameters, such as the BHDE density parameter, the equation of state parameter, the deceleration parameter, the jerk parameter and the square of sound speed. We show that our model satisfactorily retraces the thermal history of the Universe and is consistent with current observations for certain values of parameters, providing an eligible candidate to describe dark energy. We finally explore the thermodynamics of our framework, with special focus on the validity of the generalized second law.
