论文摘要
在量子宇宙学方法的框架中分析了哈勃张力。发现在量子BOHM电位规定的总能量密度的表达式中出现了新的汇总。这种额外的能量密度与僵硬的物质组件相似，修改了早期宇宙的扩展历史，并用比例因子$ a $ a $ a $ a $ a^{ - 6} $腐烂，在后期宇宙中比辐射快。在原则上，考虑到量子性质的这一问题 - 能量成分可以消除直接延迟时间独立于模型的直接测量，对哈勃常数的测量与其间接模型依赖性估计值之间的差异。考虑的模型允许人们将标准宇宙学扩展到量子部门。
The Hubble tension is analyzed in the framework of quantum cosmological approach. It is found that there arises a new summand in the expression for the total energy density stipulated by the quantum Bohm potential. This additional energy density acts similarly to a stiff matter component, modifying the expansion history of the early universe and decaying with scale factor $a$ as $a^{-6}$, faster than radiation, in late universe. Taking account of this matter-energy component of quantum nature can, in principle, eliminate a discrepancy between the direct late time model-independent measurements of the Hubble constant and its indirect model dependent estimates. The considered model allows one to extend the standard cosmology to quantum sector.
