Scaling solutions for gauge invariant flow equations in dilaton quantum gravity
Yadikaer Maitiniyazi, Christof Wetterich, Masatoshi Yamada
We discuss the ultraviolet fixed point of asymptotically safe dilaton quantum gravity. It differs from the Reuter fixed point by the dependence of the Planck mass on a scalar field…
Fermi scale from quantum gravity scaling solution
Christof Wetterich
We propose that quantum gravity may predict the Fermi scale. Fundamental scale invariance implies the scale invariant standard model. Both the Fermi scale and the Planck mass are g…
Simplified functional flow equation
C. Wetterich
We adapt the precise definition of the flowing effective action in order to obtain a functional flow equation with simple properties close to physical intuition. The simplified flo…
Field transformations in functional integral, effective action and functional flow equations
C. Wetterich
Field transformations for the quantum effective action lead to different pictures of a given physical situation, as describing a given evolution of the universe by different geomet…
