Gauge fixing is a useful tool to simplify calculations. It is also valuable to combine different methods, in particular lattice and continuum methods. However, beyond perturbation theory the Gribov-Singer ambiguity requires further gauge conditions for a well-defined gauge-fixing prescription. Different additional conditions can, in principle, lead to different results for gauge-dependent correlation functions, as will be discussed for the example of Landau gauge. Also the relation of lattice… 
On the gauge-algebra dependence of Landau-gauge Yang-Mills propagators
Yang-Mills theory can be formulated for any semi-simple Lie-algebra, and thus any semi-simple Lie-group. In principle, the dynamics could be different for each one. However, functional studies
Gauges, propagators, and physics
When a theory shall be described at all scales, it is necessary to start from its elementary degrees of freedom. Herein, one possible chain of steps for this purpose will be briefly outlined for the
Scalar-matter-gluon interaction
A full non-perturbative treatment of gauge theories requires to include matter fields on equal footing with the gauge fields. Scalar matter can act as a role model for generic matter, as many

Expectation values of coherent states for SU(2) Lattice Gauge Theories
This article investigates properties of semiclassical Gauge Field Theory Coherent States for general quantum gauge theories. Useful, e.g., for the canonical formulation of Lattice Gauge Theories
On the Infrared Behaviour of Landau Gauge Yang‐Mills Theory with Differently Charged Scalar Fields
Recently it has been argued that infrared singularities of the quark‐gluon vertex of Landau gauge QCD can confine static quarks via a linear potential. It is demonstrated that the same mechanism also
Infrared correlation functions in Quantum Chromodynamics
The aim of this thesis is to investigate the infrared behaviour of Yang-Mills correlation functions. It is known that the gauge invariance of the theory brings as a consequence the necessity of a
Phase structure of five-dimensional anisotropic lattice gauge theories
The idea that we live in a higher-dimensional space was first introduced almost 100 years ago. In the past two decades many extra-dimensional models have been proposed in order to solve fundamental
Diquarks in the nilpotency expansion of QCD and their role at finite chemical potential
We assume that the most important quark correlations are pairwise at all baryon densities. We introduce correlated pairs by means of Bogoliubov transformations which are functions of time and spatial
On the gauge boson’s properties in a candidate technicolor theory
The technicolor scenario replaces the Higgs sector of the standard model with a strongly interacting sector. One candidate for a realization of such a sector is two-technicolor Yang-Mills theory

More on Gribov copies and propagators in Landau-gauge Yang-Mills theory
Fixing a gauge in the nonperturbative domain of Yang-Mills theory is a nontrivial problem due to the presence of Gribov copies. In particular, there are different gauges in the nonperturbative regime

The infrared behaviour of QCD Green's functions in Landau gauge has been focus of intense study. Different non-perturbative approaches lead to a prediction in line with the conditions for confinement
Modified Lattice Landau Gauge
We propose a modified lattice Landau gauge based on stereographically projecting the link variables on the circle S^1 -> R for compact U(1) or the 3-sphere S^3 -> R^3 for SU(2) before imposing the
