标题： Holographic dark energy through Loop Quantum Gravity inspired entropy

摘要： 我们构建了一个新的宇宙全息暗能量场景，该场景基于圈量子引力启发的熵，而不是标准的贝肯斯坦-霍金熵。前者是一种从非广延统计和量子几何中产生的扩展黑洞熵，并由一个新的无量纲参数$q$来量化，该参数将标准全息暗能量作为特定子情况。在未来的事件视界作为红外截断的情况下，我们给出了暗能量密度参数的简单微分方程，以及相应的状态方程和减速参数的解析表达式。我们表明，当前的场景可以成功描述宇宙的常规热历史，包括物质和暗能时期序列，而加速过渡发生在$z\approx 0.6$。此外，根据新熵参数$q$的值，暗能量状态方程参数可以表现出丰富的行为，它可以是第五元素类似、幻影类似，或者经历幻影分割穿越。 显示英文摘要

摘要： We construct a new cosmological holographic dark energy scenario based on Loop Quantum Gravity inspired entropy, instead of the standard Bekenstein-Hawking one. The former is an extended black-hole entropy that arises from non-extensive statistics and quantum geometry and is quantified by a new dimensionless parameter $q$, which possesses standard holographic dark energy as a particular sub-case. In the future event horizon as the Infrared cutoff, we provide a simple differential equation for the dark energy density parameter, as well as an analytical expressions for the corresponding equation-of-state and deceleration parameters. We show that the scenario at hand can describe successfully the usual thermal history of the Universe, with the sequence of matter and dark-energy epochs, while the transition to acceleration takes place at $z\approx 0.6$. Additionally, according to the value of the new entropic parameter $q$, the dark energy equation-of-state parameter can have a rich behavior, and it can be quintessence-like, phantom-like, or experience the phantom-divide crossing.
