论文摘要
在本文中，我们讨论了在Trans-Planckian审查制度猜想（TCC）的条件下增强张量比比率$ r $的可能性，因此可以在未来实验的敏感性中观察到$ r \ sim O（10^{ - 3}）$。我们利用标量调整理论，在该理论中，充气与重力无限耦合。在证明TCC条件可以通过标量张量理论进行修改之后，我们表明，由于通货膨胀结束时修饰的重力的影响，可以允许不违反TCC的大型$ r \ sim o（10^{ - 3}）$。此外，修饰会导致重力与通货膨胀场的耦合较弱。如果早在通货膨胀开始时就已经出现了这种影响，这意味着在我们的情况下，宇宙可能在早期经历了渐近的安全时期。
In this paper, we discuss about the possibility to enhance the tensor-to-scalar ratio $r$ under the condition of Trans-Planckian censorship conjecture (TCC), thus $r\sim O(10^{-3})$ could be observable within the sensitivity of future experiments. We make use of the scalar-tensor theory where inflaton is nonminimally coupled to gravity. After demonstrating that the TCC condition could be modified in scalar-tensor theory, we show that due to the effects of modified gravity at the end of inflation, a large $r\sim O(10^{-3})$ could be allowed without violating the TCC. Moreover, the modification can give rise to a weak coupling of gravity to the inflation field. If such an effect has been present as early as inflation starts, it would imply that in our case, the Universe might have experienced an asymptotically safe period at its early time.
