Form Factors in Quantum Gravity - contrasting non-local, ghost-free gravity and Asymptotic Safety
Benjamin Knorr, Chris Ripken, Frank Saueressig
Form factors constitute the key building block when organising the gravitational dynamics in terms of a curvature expansion. They generalise the concept of momentum-dependent coupl…

Non-perturbative propagators in quantum gravity
Benjamin Knorr, Marc Schiffer
We employ non-perturbative renormalisation group methods to compute the full momentum dependence of propagators in quantum gravity in general dimensions. We disentangle all differe…

The derivative expansion in asymptotically safe quantum gravity: general setup and quartic order
Benjamin Knorr
We present a general framework to systematically study the derivative expansion of asymptotically safe quantum gravity. It is based on an exact decoupling and cancellation of diffe…
