Smooth Threshold Effects from Dimensional Regularization
Yannick Kluth
We suggest a non-minimal renormalization scheme based on dimensional regularization that naturally incorporates threshold effects of heavy particles. By renormalizing couplings and…
The perturbative Ricci flow in gravity
Robert V. Harlander, Yannick Kluth, Jonas T. Kohnen +1
We develop a perturbative formulation of the Ricci flow in gravity. Following steps analogous to the gradient flow in QCD, we supplement the usual Feynman rules for perturbative gr…
Fixed Points of Quantum Gravity from Dimensional Regularisation
Yannick Kluth
We investigate -functions of quantum gravity using dimensional regularisation. In contrast to minimal subtraction, a non-minimal renormalisation scheme is employed which is sens…
Robustness of the derivative expansion in Asymptotic Safety
Alessio Baldazzi, Kevin Falls, Yannick Kluth +1
We analyse the renormalisation group flow of quantum gravity at sixth order in the derivative expansion within the background field approximation. Non-linear field redefinitions ar…
Renormalization group flows from the Hessian geometry of quantum effective actions
Yannick Kluth, Peter Millington, Paul Saffin
We explore a geometric perspective on quantum field theory by considering the configuration space, where all field configurations reside. Employing -particle irreducible effecti…
Spectral Functions of Gauge Theories with Banks-Zaks Fixed Points
Yannick Kluth, Daniel Litim, Manuel Reichert
We investigate spectral functions of matter-gauge theories that are asymptotically free in the ultraviolet and display a Banks-Zaks conformal fixed point in the infrared. Using per…
Functional Renormalisation for Quantum Gravity
Yannick Kluth, Daniel F. Litim
We derive new functional renormalisation group flows for quantum gravity, in any dimension. The key new achievement is that the equations apply for any theory of gravity whose unde…
Fixed Points of Quantum Gravity and the Dimensionality of the UV Critical Surface
Yannick Kluth, Daniel Litim
We study quantum effects in higher curvature extensions of general relativity using the functional renormalisation group. New flow equations are derived for general classes of mode…
Heat kernel coefficients on the sphere in any dimension
Yannick Kluth, Daniel F. Litim
We derive all heat kernel coefficients for Laplacians acting on scalars, vectors, and tensors on fully symmetric spaces, in any dimension. Final expressions are easy to evaluate an…
