Quantum gravitational corrections from the Wheeler-DeWitt equation for scalar-tensor theories
Christian F. Steinwachs, Matthijs L. van der Wild
We perform the canonical quantization of a general scalar-tensor theory and derive the first quantum gravitational corrections following from a semi-classical expansion of the Whee…
Quantum equivalence of gravity and scalar-tensor theories
Michael S. Ruf, Christian F. Steinwachs
We investigate whether the classical equivalence of gravity and its formulation as scalar-tensor theory still holds at the quantum level. We explicitly compare the correspon…
One-loop divergences for gravity
Michael S. Ruf, Christian F. Steinwachs
We calculate the divergent part of the one-loop effective action for gravity on an arbitrary background manifold. Our result generalizes previous results for quantum correct…
Hořava gravity is asymptotically free (in 2+1 dimensions)
Andrei O. Barvinsky, Diego Blas, Mario Herrero-Valea +2
We compute the -functions of marginal couplings in projectable Hořava gravity in spacetime dimensions. We show that the renormalization group flow has an asymptotically-fr…
Renormalization of gauge theories in the background-field approach
Andrei O. Barvinsky, Diego Blas, Mario Herrero-Valea +2
Using the background-field method we demonstrate the Becchi-Rouet-Stora-Tyutin (BRST) structure of counterterms in a broad class of gauge theories. Put simply, we show that gauge i…
Heat kernel methods for Lifshitz theories
Andrei O. Barvinsky, Diego Blas, Mario Herrero-Valea +3
We study the one-loop covariant effective action of Lifshitz theories using the heat kernel technique. The characteristic feature of Lifshitz theories is an anisotropic scaling bet…
