Abstract
AbstractWe 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 $$\Gamma _0$$
Γ
0
by integrating the flow equation from the ultraviolet scale down to $$k=0$$
k
=
0
. The resulting effective action consists of local terms and nonlocal terms with unique coefficients.
