论文摘要
已经计算了封闭的DE Sitter Universe的波函数，要求与最近提出的Trans-Planckian审查猜想（TCC）保持一致。我们将爱因斯坦 - 希尔伯特的作用扩展到包含一个复杂的价值项，该项为违反Lorentzian路径积分总和的几何形状提供了指数衰减的权重，而在MinisuperSpace的方法中进行量子宇宙学的方法。此\ textit {假定}修改抑制了宇宙演变成违反TCC的配置的概率。我们表明，由于存在这种抑制因子，通货膨胀结束时宇宙的哈勃速率被屈服了，并假定值小于经典期望的值。此外，还讨论了原始功率谱系中这种量子重力校正的后果。
The wave function for a closed de Sitter universe has been computed, demanding consistency with the recently proposed Trans-Planckian Censorship Conjecture (TCC). We extend the Einstein-Hilbert action to contain a complex-valued term which provides an exponentially decaying weight for the geometries violating TCC in the Lorentzian path integral sum while working in the minisuperspace approach to quantum cosmology. This \textit{postulated} modification suppresses the probability of evolution of the universe into configurations that violate TCC. We show that due to the presence of this suppression factor, the Hubble rate of the universe at the end of the inflation gets subdued and assumes a value less than what is expected classically. Moreover, the consequences of this quantum gravity motivated correction in the primordial power spectrum are discussed as well.
