Chiral symmetry restoration effects onto the meson spectrum from a Dyson-Schwinger and Bethe-Salpeter approach
Reinhard Alkofer, Christian S. Fischer, Fabian Zierler
Light meson spectra are studied in a Dyson-Schwinger/Bethe-Salpeter approach to QCD. By varying the interaction strength of three sets of models for the quark-antiquark interaction…
The role of frequency dependence in dynamical gap generation in graphene
M. E. Carrington, C. S. Fischer, L. von Smekal +1
We study the frequency dependencies of the fermion and photon dressing functions in dynamical gap generation in graphene. We use a low energy effective QED-like description, but wi…
Dynamical gap generation in graphene with frequency dependent renormalization effects
M. E. Carrington, C. S. Fischer, L. von Smekal +1
We study the frequency dependencies in the renormalization of the fermion Greens function for the -band electrons in graphene and their influence on the dynamical gap generation…
Studying pion effects on the chiral phase transition
J. A. Mueller, C. S. Fischer
We investigate the chiral phase transition at finite temperatures and zero chemical potential with Dyson-Schwinger equations. Our truncation for the quark-gluon interaction include…
Lower dimensional Yang-Mills theory as a laboratory to study the infrared regime
Reinhard Alkofer, Christian S. Fischer, Markus Q. Huber +1
Lattice studies of the infrared regime of gauge theories are complicated by the required extensive limits, the performed gauge fixing and the demand for high statistics. Using a ge…
What the Infrared Behaviour of QCD Vertex Functions in Landau gauge can tell us about Confinement
R. Alkofer, C. S. Fischer, F. Llanes-Estrada +1
The infrared behaviour of Landau gauge QCD vertex functions is investigated employing a skeleton expansion of the Dyson-Schwinger and Renormalization Group equations. Results for t…
