论文摘要
在$λ$ CDM模型中，暗能量被视为恒定的真空能量密度，即爱因斯坦 - 希尔伯特动作中的宇宙常数。在引入动态黑能的各种模型中可以放松这个假设。在这封信中，我们认为，量子重力中的红外和紫外线自由度之间的混合导致无限统计，这是与洛伦兹在非局部性存在下不变性一致的独特统计数据，并产生了深色能量的良好结构。将IR和UV截止值引入量子重力动作中，我们推断出$λ$的形式，作为红移的函数，并将其转化为哈勃参数的行为。
In the $Λ$CDM model, dark energy is viewed as a constant vacuum energy density, the cosmological constant in the Einstein--Hilbert action. This assumption can be relaxed in various models that introduce a dynamical dark energy. In this letter, we argue that the mixing between infrared and ultraviolet degrees of freedom in quantum gravity lead to infinite statistics, the unique statistics consistent with Lorentz invariance in the presence of non-locality, and yield a fine structure for dark energy. Introducing IR and UV cutoffs into the quantum gravity action, we deduce the form of $Λ$ as a function of redshift and translate this to the behavior of the Hubble parameter.
