泛函重整化群的有效Action

Effective Action from the Functional Renormalization Group

Nobuyoshi Ohta, Leslaw Rachwal

摘要:

我们研究了耦合到带电标量、狄拉克费米子和电磁场的量子引力系统。我们使用“精确的”或“功能”的重整化群方程,推导出有效的行动$Γ_0$通过积分的流量方程从紫外尺度下到$k=0$。所得到的有效作用量由局部项和非局部项组成,具有唯一的系数。

英文摘要:

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.
