我们评论了Senatore和Zaldarriaga最近的论点,即ζ -ζ相关器的循环修正在第一次视界穿越后不能随时间增长。我们首先强调在无限空间流形上输入-输出矩阵元素为红外奇异的修正中寻找这种长期依赖的必要性。然后给出了纯量子引力和标量势模型的时间依赖的例子。最后,我们指出,这种时间依赖性来自暴胀粒子的产生,因此不太可能危及作为暴胀记录的超视界相关性的保存。
We comment on the recent arguments by Senatore and Zaldarriaga that loop corrections to the ζ–ζ correlator cannot grow with time after first horizon crossing. We first emphasize the need to search for such secular dependence in corrections whose in–out matrix elements are infrared singular on an infinite spatial manifold. Then we give examples of such time dependence from pure quantum gravity and from scalar potential models. Finally, we point out that this time dependence arises from inflationary particle production and is therefore unlikely to endanger the preservation of super-horizon correlations as a record of inflation.
