Hořava's quantum gravity at a Lifshitz point is a theory intended to quantize gravity by using
traditional quantum field theories. To avoid Ostrogradsky's ghosts, a problem that has been …

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 …

A bstract We explore the impact of asymptotically safe quantum gravity on the Abelian gauge
coupling in a model including a charged scalar, confirming indications that asymptotically …

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 …

We critically examine the gauge and field-parametrization dependence of renormalization
group flows in the vicinity of non-Gaußian fixed points in quantum gravity. While physical …

Asymptotic safety provides a mechanism for constructing a consistent and predictive
quantum theory of gravity valid on all length scales. Its key ingredient is a non-Gaussian …

We use the functional renormalization group equation for the effective average action to
study the non-Gaussian renormalization group fixed points (NGFPs) arising within the …

We highlight how the existence of an ultraviolet completion for interacting standard-model
type matter puts constraints on the viable microscopic dynamics of asymptotically safe …

We study four-dimensional quantum gravity using nonperturbative renormalization group
methods. We solve the corresponding equations for the fully momentum-dependent …

We study the fixed-point structure of the Higgs–Yukawa model, with its scalar being non-
minimally coupled to the asymptotically safe gravity, using the functional renormalization …
