  1. 184. Searching for calorons and dyons in SU(3) gluodynamic near to the transition and in deconfinement with the help of near-zero overlap modes
    Dr Ernst-Michael Ilgenfritz (JINR Dubna, VBLHEP and BLTP)

    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...

  2. 224. Dynamical Chiral Polarization of QCD Dirac Spectrum
    Ivan Horvath (University of Kentucky)

    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.

  3. 91. How center vortices break chiral symmetry
    Manfried Faber (VUT)

    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...

  4. 16. A model of random center vortex lines in continuous 2+1 dimensional space-time
    Dr Roman Höllwieser (NMSU/VUT)
    12/09/2014, 15:30
    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....
