Unsupervised energy disaggregation via convolutional sparse coding
Christian Aarset, Andreas Habring, Martin Holler +1
In this work, a method for unsupervised energy disaggregation in private households equipped with smart meters is proposed. This method aims to classify power consumption as active…
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…

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)…
Center phase transition from matter propagators in (scalar) QCD
M. Mitter, M. Hopfer, B. -J. Schaefer +1
Novel order parameters for the confinement-deconfinement phase transition of quenched QCD and fundamentally charged scalar QCD are presented. Similar to the well-known dual condens…
Non-perturbative finite-temperature Yang-Mills theory
Anton K. Cyrol, Mario Mitter, Jan M. Pawlowski +1
We present non-perturbative correlation functions in Landau-gauge Yang-Mills theory at finite temperature. The results are obtained from the functional renormalisation group within…
Non-perturbative quark, gluon and meson correlators of unquenched QCD
Anton K. Cyrol, Mario Mitter, Jan M. Pawlowski +1
We present non-perturbative first-principle results for quark-, gluon- and meson PI correlation functions of two-flavour Landau-gauge QCD in the vacuum. These correlation functi…
FormTracer - A Mathematica Tracing Package Using FORM
Anton K. Cyrol, Mario Mitter, Nils Strodthoff
We present FormTracer, a high-performance, general purpose, easy-to-use Mathematica tracing package which uses FORM. It supports arbitrary space and spinor dimensions as well as an…
Landau gauge Yang-Mills correlation functions
Anton K. Cyrol, Leonard Fister, Mario Mitter +2
We investigate Landau gauge Yang-Mills theory in a systematic vertex expansion scheme for the effective action with the functional renormalisation group. Particular focus i…
Pion and -meson mass splitting at the two-flavour chiral crossover
Markus Heller, Mario Mitter
We study the splitting in the screening mass of pions and the -meson across the chiral crossover. This splitting is determined by the 't Hooft determinant. We use results for th…
Chiral symmetry breaking in continuum QCD
Mario Mitter, Jan M. Pawlowski, Nils Strodthoff
We present a quantitative analysis of chiral symmetry breaking in two-flavour continuum QCD in the quenched limit. The theory is set-up at perturbative momenta, where asymptotic fr…
On propagators and vertices of Landau gauge Yang-Mills theory
Markus Q. Huber, Adrian Lorenz Blum, Mario Mitter +1
We calculate the three-point functions of pure Landau gauge QCD and investigate their influence on the propagators. As expected, the ghost-gluon vertex leads only to minor modifica…
Exploring the Phase Structure and Thermodynamics of QCD
Tina K. Herbst, Mario Mitter, Jan M. Pawlowski +2
We put forward a Polyakov-loop extended quark meson model, where matter as well as glue fluctuations are taken into account, cf. [1]. The latter are included via a Polyakov-loop po…
Gluonic three-point correlations in pure Landau gauge QCD

We report on the first self-consistent solution of the Dyson-Schwinger equation (DSE) for the three-gluon vertex. Based on earlier results for the propagators which match data from…

We study the phase structure of QCD at finite temperature within a Polyakov-loop enhanced quark-meson model. Such a model describes the chiral as well as the confinement-deconfinem…
