论文摘要
抗DE保姆（ADS）黑洞在全息原理中起着重要作用。在这项研究中，对应于Schwarzschild黑洞质量的能量的上限被修饰为广告黑洞的质量。通过紫外线（UV）和红外（IR）截止之间的对应关系，可以从黑洞的负宇宙常数中获得全息暗能量（HDE）的能量密度的恒定项。有趣的是，拟议的暗能量模型可以在不违反因果关系的情况下推动宇宙的延迟扩展。通过选择Hubble和粒子范围作为IR长度尺度来研究宇宙进化。发现两种情况下都可以在晚期获得加速扩张。该结果可能会阐明广告黑洞与宇宙学上的DE Sitter（DS）时空之间的连接。
The anti-de Sitter (AdS) black hole plays an important role in the holographic principle. In this study, the upper bound in energy corresponding to the mass of the Schwarzschild black hole is modified to be that of the AdS black hole. Via the correspondence between the ultraviolet (UV) and infrared (IR) cutoffs, the constant term in the energy density of the holographic dark energy (HDE) can be obtained from the negative cosmological constant from the black hole. Interestingly, the proposed dark energy model could drive the late-time expansion of the Universe without the causality violation. The cosmic evolution is investigated by choosing the Hubble and particle horizons as the IR length scales. It is found that the accelerated expansion at late time can be obtained for both cases. This result may shed light on the connection between the AdS black hole and the de Sitter (dS) spacetime in the context of cosmology.
