Section A: Vacuum Structure and Confinement
The topological structure of $SU(3)$ gluodynamics close to the infrared scale
is studied near to the transition temperature with the help of zero and
near-zero modes of the overlap Dirac operator. The associated UV filtered
topological charge density is considered for antiperiodic and two other
thermal boundary conditions. In this way three types of localized topological
clusters can be...

Section A: Vacuum Structure and Confinement
Dynamical polarization methods offer a novel way to characterize vacuum correlations of strong interactions in a model-independent manner. Selected aspects of this description are discussed with applications both for confinement and spontaneous chiral symmetry breaking.

Section A: Vacuum Structure and Confinement
We analyze the creation of near-zero modes from would-be zero modes of various topological charge contributions from classical center vortices in SU(2) lattice gauge theory. We show that colorful spherical vortex and instanton configurations have very similar Dirac eigenmodes and also vortex intersections are able to give rise to a finite density of near-zero modes, leading to chiral symmetry...

Section A: Vacuum Structure and Confinement
A promising picture of confinement in QCD is based on a condensate of thick vortices with fluxes in the center of the gauge group (center vortices). A number of studies of this picture have been made and specific models have been formulated to obtain a concrete realization of the vortex picture. In our model,
vortices are represented by closed random lines in 2+1- dimensional space-time....
