论文摘要
我们研究量子引力系统，与带电的标量，迪拉克费米子和电磁场耦合。我们使用“精确”或“功能”重新归一化组方程来得出有效的动作$γ_0$，通过将流程方程从紫外线刻度集成到$ k = 0 $。由此产生的有效动作由本地术语和非本地术语组成，具有独特的系数。
We study the quantum gravitational system coupled to a charged scalar, Dirac fermions, and electromagnetic fields. We use the "exact" or "functional" renormalization group equation to derive the effective action $Γ_0$ by integrating the flow equation from the ultraviolet scale down to $k=0$. The resulting effective action consists of local terms and nonlocal terms with unique coefficients.
