论文摘要
在这项工作中，我们研究了在渐近安全性的背景下，共同减少量子重力的截断，包括所有可以在这种截断中解决的操作员，包括最高第六阶衍生物。固定点分析表明，一旦人们超出了爱因斯坦 - 希尔伯特的近似，该系统中没有渐近安全的固定点。我们将这些发现将这些发现纳入上下文，并讨论可以从这些结果中学到的一些经验教训，以供一般的非扰动重置化群体流动。
In this work we study a significantly enlarged truncation of conformally reduced quantum gravity in the context of Asymptotic Safety, including all operators that can be resolved in such a truncation including up to the sixth order in derivatives. A fixed point analysis suggests that there is no asymptotically safe fixed point in this system once one goes beyond an Einstein-Hilbert approximation. We will put these findings into context and discuss some lessons that can be learned from these results for general non-perturbative renormalisation group flows.
