Partial bosonisation for the two-dimensional Hubbard model: How well does it work?
Tobias Denz, Mario Mitter, Jan M. Pawlowski +2
Partial bosonisation of the two-dimensional Hubbard model focuses the functional renormalisation flow on channels in which interactions become strong and local order sets in. We co…
Low-energy limit of the O(4) quark-meson model
Jürgen Eser, Florian Divotgey, Mario Mitter
We study the generation of low-energy couplings induced by quantum fluctuations within the O(4)-symmetric quark-meson model. To this end, we compute the functional renormalization…
Dynamical generation of low-energy couplings from quark-meson fluctuations
Florian Divotgey, Jürgen Eser, Mario Mitter
We extend our recent computation of the low-energy limit of the linear O(4) Quark-Meson Model. The present analysis focuses on the transformation of the resulting effective action…
Bound state properties from the Functional Renormalisation Group
Reinhard Alkofer, Axel Maas, Walid Ahmed Mian +4
We discuss an approach for accessing bound state properties, like mass and decay width, of a theory within the functional renormalisation group approach. An important cornerstone i…
Correlation functions of three-dimensional Yang-Mills theory from the FRG
Lukas Corell, Anton K. Cyrol, Mario Mitter +2
We compute correlation functions of three-dimensional Landau-gauge Yang-Mills theory with the Functional Renormalisation Group. Starting from the classical action as only input, we…
Low-energy limit of the quark-meson model from the functional renormalization group approach
Jürgen Eser, Florian Divotgey, Mario Mitter +1
We compute the low-energy limit of the -symmetric quark-meson model as an effective field theory for Quantum Chromodynamics within the Functional Renormalization Group (FRG)…
