On selfdual spin-connections and Asymptotic Safety
Ulrich Harst, Martin Reuter
We explore Euclidean quantum gravity using the tetrad field together with a selfdual or anti-selfdual spin-connection as the basic field variables. Setting up a functional renormal…
A new functional flow equation for Einstein-Cartan quantum gravity
Ulrich Harst, Martin Reuter
We construct a special-purpose functional flow equation which facilitates non-perturbative renormalization group (RG) studies on theory spaces involving a large number of independe…
The "tetrad only" theory space: Nonperturbative renormalization flow and Asymptotic Safety
Ulrich Harst, Martin Reuter
We set up a nonperturbative gravitational coarse graining flow and the corresponding functional renormalization group equation on the as to yet unexplored "tetrad only" theory spac…
QED coupled to QEG
Ulrich Harst, Martin Reuter
We discuss the non-perturbative renormalization group flow of Quantum Electrodynamics (QED) coupled to Quantum Einstein Gravity (QEG) and explore the possibilities for defining its…
Running Gauge Coupling in Asymptotically Safe Quantum Gravity
Jan-Eric Daum, Ulrich Harst, Martin Reuter
We investigate the non-perturbative renormalization group behavior of the gauge coupling constant using a truncated form of the functional flow equation for the effective average a…
