Fractal geometry of higher derivative gravity

arXiv:1911.02415 · doi:10.1103/PhysRevLett.124.151302

Abstract

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 operators. We use these results to deduce the fractal dimensions of such hypersurfaces embedded in a quantum spacetime at very small distances.
