AI 中文摘要
本文通过Weyl-Wigner量子力学框架重新研究了包含所谓哈勃张力问题的解析解，并在量子宇宙学的广义相空间场景下进行了讨论。在回顾该问题的本质及其最新进展后，本文提出了一种在量子相空间框架内构建的扩展公式，用于解决哈勃张力问题。对于通过（通用）局域相空间量子态在minisuperspace框架下描述的量子宇宙学，当解析推导爱因斯坦-弗里德曼方程的残余量子修正时，量子效应被证明能抑制早期和晚期预测之间的哈勃张力发散。除了在标准ΛCDM宇宙学模型内解决哈勃张力问题外，本文的方法还涵盖了包含曲率和暗 sector 修正的广义量子宇宙学场景。
英文摘要
Analytical solutions encompassing the so-called Hubble tension problem are revisited through the framework of Weyl--Wigner quantum mechanics and discussed in the context of generalized phase-space scenarios of quantum cosmology. After reviewing the nature of the problem and its recent developments, an extended formulation constructed within the quantum phase-space framework to address the Hubble tension is proposed. For the quantum cosmology described in the minisuperspace framework through (generic) localized phase-space quantum states, when residual quantum corrections to the Einstein--Friedmann equation are analytically derived, quantum effects are shown to suppress the Hubble tension divergence between early- and late-time predictions. Besides addressing the Hubble tension problem within the standard $Λ$CDM cosmological model, our approach encompasses generalized quantum cosmological scenarios that also include curvature and dark sector modifications.
