Infinite order quantum-gravitational correlations
Benjamin Knorr
A new approximation scheme for nonperturbative renormalisation group equations for quantum gravity is introduced. Correlation functions of arbitrarily high order can be studied by…

Critical (Chiral) Heisenberg Model with the Functional Renormalisation Group
Benjamin Knorr
We discuss the Heisenberg model and its chiral extension in an extended truncation with the help of functional methods. Employing computer algebra to derive the beta functions, and…

Correlation functions on a curved background
Benjamin Knorr, Stefan Lippoldt
We investigate gravitational correlation functions in a curved background with the help of nonperturbative renormalization group methods. Beta functions for eleven couplings are de…
