论文摘要
我们提出了一个基于批判现象的物理学的暗能模型，该模型与普朗克的CMB和Riess等人的本地哈勃测量结果一致。在此模型中，暗能量密度与Ising模型的磁化一样。这意味着黑暗能量是一种新兴现象，我们将其命名为重要的黑暗能量模型Cede。在CEDE中，暗能量以$ z_c $的过渡红移出现，对应于关键现象中的临界温度。结合了Planck CMB数据和Riess等人的哈勃常数的局部测量。 （2019年）我们发现，相对于非常早期过渡的情况，对这一过渡的统计学显着支持，该过渡有效地代表了宇宙常数。这是可以理解的，因为CEDE模型自然更喜欢与局部测量一致的较大的哈勃恒定值。由于Cede更喜欢非平凡的过渡，当我们考虑高红移Planck CMB数据和局部哈勃恒定测量值时，我们得出结论，$ H_0 $张力可以暗示黑暗能量作为临界现象的良好特性的黑暗能量的子结构。
We propose a dark energy model based on the physics of critical phenomena which is consistent with both the Planck's CMB and the Riess et al.'s local Hubble measurements. In this model the dark energy density behaves like the magnetization of the Ising model. This means the dark energy is an emergent phenomenon and we named it critically emergent dark energy model, CEDE. In CEDE, dark energy emerges at a transition redshift, $z_c$, corresponding to the critical temperature in critical phenomena. Combining the Planck CMB data and local measurement of the Hubble constant from Riess et al. (2019) we find statistically significant support for this transition with respect to the case of very early transition that represents effectively the cosmological constant. This is understandable since CEDE model naturally prefers larger values of Hubble constant consistent with local measurements. Since CEDE prefers a non-trivial transition when we consider both high redshift Planck CMB data and local Hubble constant measurements, we conclude that $H_0$ tension can be a hint for the substructure of the dark energy as a well-studied properties of critical phenomena.
