Fractal geometry of higher derivative gravity
Maximilian Becker, Carlo Pagani, Omar Zanusso
We determine the scaling properties of geometric operators such as lengths, areas, and volumes in models of higher derivative quantum gravity by renormalizing appropriate composite…

Background Independent Quantum Field Theory and Gravitating Vacuum Fluctuations
Carlo Pagani, Martin Reuter
The scale dependent effective average action for quantum gravity complies with the fundamental principle of Background Independence. Ultimately the background metric it formally de…
