We calculate the one loop graviton vacuum polarization induced by a massless, nonminimally coupled scalar field on Minkowski background. We make use of the Schwinger-Keldysh formalism, which allows us to study time dependent phenomena. As an application we compute the leading quantum correction to the Newtonian potential of a point particle. The novel aspect of the calculation is the use of the Schwinger-Keldysh formalism, within which we calculate the time transients induced by switching on of the graviton-scalar coupling.

The first terms in Eqs. ([ref]–[ref]) represent the one-loop contributions from a conformal scalar field, and in the limit when $H→0, a→1$ they reduce to the Minkowski space results of Refs. [ref] , representing a nontrivial check of our principal results ([ref]–[ref]).

This is in strong contrast to existing quantum gravitational results at one-loop order, e.g., the corrections to the Newtonian potential [ref] , where the result is unambiguous for separated points and the dependence on the finite parts of higher-derivative counterterms only appears at coincidence.

Hints that the mechanism of singularity-avoidance could be realized within the Asymptotic Safety scenario for Quantum Gravity have been found in [ref] via the so-called RG-improvement procedure (see, e.g., [ref] and references therein), in [ref] by means of non-perturbative computations of quantum corrections to the Newtonian potential based on the functional renormalization group (FRG) method, and in [ref] through a one-particle irreducible resummation of one-loop vacuum fluctuations of non-minimally coupled, massless, scalar matter.

This is the generalization of the graviton vacuum polarization induced by a minimally coupled scalar ($ξ=0$) calculated by Park and Woodard in [ref] to the case of a massless, nonminimally coupled, scalar ($ξ≠0$), and it is one of the main results of this work.
