Abstract
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 by integrating the flow equation from the ultraviolet scale down to . The resulting effective action consists of local terms and nonlocal terms with unique coefficients.
