Description
In this talk, I will review aspects of the fluctuation approach to metric quantum gravity. This approach disentangles dynamical metric fluctuations from the background metric, which allows to fulfil diffeomorphism symmetry constraints on the flow and to employ the systematic vertex expansion schemes. I will highlight important results such as momentum-dependent correlation functions at vanishing cutoff scale, the phase structure of the asymptotically safe Standard Model, and spectral properties of asymptotically safe gravity from direct computations in space-times with Lorentzian signatures such as the graviton spectral function.
