Abstract

We present the first attempt to find the holographic interpretation of running of the Newton's constant in 4-dimensional quantum theory. We compute its scale-dependence using functional renormalization group methods based on aWilsonian momentum cutoff.We show the details of the corresponding holographic RG flow in 5-dimensional spacetime with minimally coupled scalar field in the bulk. In this domain wall setup the scalar potential is found. Solutions of this theory describe RG flows of gravitational coupling with the IR threshold phenomena fully taken into account. � 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
