Generalized Parametrization Dependence in Quantum Gravity
Holger Gies, Benjamin Knorr, Stefan Lippoldt
We critically examine the gauge, and field-parametrization dependence of renormalization group flows in the vicinity of non-Gaußian fixed points in quantum gravity. While physical…
Local Quantum Gravity
Nicolai Christiansen, Benjamin Knorr, Jan Meibohm +2
We investigate the ultraviolet behaviour of quantum gravity within a functional renormalisation group approach. The present setup includes the full ghost and graviton propagators a…
Global solutions of functional fixed point equations via pseudo-spectral methods
Julia Borchardt, Benjamin Knorr
We apply pseudo-spectral methods to construct global solutions of functional renormalisation group equations in field space to high accuracy. For this, we introduce a basis to reso…
