论文摘要
基于全息原理和手推车熵，已经提出了巴罗全息暗能。为了分析巴罗全息暗能量的稳定性和演变，我们在本文中，将动力学分析和态 - 结果方法应用于带有不同IR截止和相互作用术语的Barrow全息暗能量。在使用Hubble Horizon用作IR截止的情况下，与交互项$ q = \fracλ{h}ρ_{m}ρ_{d} $，我们发现该模型是稳定的，可以用来描述宇宙的整个宇宙演化，当能量传输从压力无压的小桶式Hotolow Hologrophic Dark Energion中无关紧要。当将动态分析方法应用于此稳定模型时，存在与加速膨胀时期相对应的吸引子，并且该吸引子可以作为宇宙常数。此外，在这种情况下可以解决巧合问题。然后，在对该模型使用了状态基调分析方法之后，我们发现该模型可以与标准$λ$ CDM模型区分开。最后，我们讨论了巴罗全息暗能量中哈勃图的转折点，并发现该模型中不存在转折点。
Based on the holographic principle and the Barrow entropy, Barrow holographic dark energy had been proposed. In order to analyze the stability and the evolution of Barrow holographic dark energy, we, in this paper, apply the dynamical analysis and statefinder methods to Barrow holographic dark energy with different IR cutoff and interacting terms. In the case of using Hubble horizon as IR cutoff with the interacting term $Q=\fracλ{H}ρ_{m}ρ_{D}$, we find this model is stable and can be used to describe the whole evolution of the universe when the energy transfers from the pressureless matter to the Barrow holographic dark energy. When the dynamical analysis method is applied to this stable model, an attractor corresponding to an accelerated expansion epoch exists and this attractor can behave as the cosmological constant. Furthermore, the coincidence problem can be solved in this case. Then, after using the statefinder analysis method to this model, we find this model can be discriminated from the standard $Λ$CDM model. Finally, we have discussed the turning point of Hubble diagram in Barrow holographic dark energy and find the turning point does not exist in this model.
