The renormalization group plays an essential role in many areas of physics, both
conceptually and as a practical tool to determine the long-distance low-energy properties of …

Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field
theories, in particular for quantum gravity. Significant progress on this program has led to a …

We give a pedagogical introduction to the basic ideas and concepts of the Asymptotic Safety
program in quantum Einstein gravity. Using the continuum approach based upon the …

The asymptotic safety conjecture is examined for quantum gravity in four dimensions. Using
the renormalization group, we find evidence for an interacting UV fixed point for polynomial …

Over the last years the asymptotic safety program has matured into a serious candidate for a
quantum theory of gravity compatible with observations. The rapid technical progress in …

Weinberg's asymptotic safety scenario provides an elegant mechanism to construct a
quantum theory of gravity within the framework of quantum field theory based on a non …

We study the ultraviolet complete non-relativistic theory recently proposed by Hořava. After
introducing a Lifshitz scalar for a general background, we analyze the cosmology of the …

A bstract Asymptotic Safety provides an elegant mechanism for obtaining a consistent high-
energy completion of gravity and gravity-matter systems. Following the initial idea by Steven …

A key incentive of quantum gravity is the removal of spacetime singularities plaguing the
classical theory. We compute the nonperturbative momentum dependence of a specific …

A bstract We employ the Arnowitt-Deser-Misner formalism to study the renormalization group
flow of gravity minimally coupled to an arbitrary number of scalar, vector, and Dirac fields …
