We discuss the subtleties concerning the lattice computation of the ghost propagator in linear covariant gauges, and present preliminary numerical results.

We report on the chromoelectric and chromomagnetic fields generated
by a static quark-antiquark pair at zero temperature in pure gauge SU(3).
From the spatial structure of chromoelectric field we extract its nonperturbative
part and discuss its properties.

Vacuum Structure and Confinement
Dual superconductor picture is a promising scenario for quark confinement. For quarks in the fundamental representation, we have presented a new formulation of Yang-Mills theory on the lattice, where decomposed restricted fields play the dominant role in confinement, and demonstrated numerical evidences for the dual superconductivity. To establish this picture, we must show evidences for...

We study the spatial distribution of the stress tensor around static quark-anti-quark pair
in SU(3) lattice gauge theory. In particular, we reveal the transverse structure of the stress tensor distribution in detail by taking the continuum limit. The Yang-Mills gradient flow plays a crucial role to make the stress tensor well-defined and derivable from the numerical simulations on the lattice...

This presentation examines the structure of centre vortices in Monte-Carlo generated gauge-field configurations using modern visualization techniques. We'll begin with a brief review of how centre vortices underpin dynamical chiral symmetry breaking and how their removal restores chiral symmetry.
Centre vortices are identified through gauge transformations maximizing the centre of the...

It is known that at high temperature the lowest eigenmodes of the QCD Dirac
operator become localized. Since these localized modes appear around the cross-over
temperature it is natural to ask how they are related to deconfinement and
chiral symmetry restoration. The simplest question one can ask in this connection is
whether deconfinement and the appearance of localization happen at the...

At high temperature part of the spectrum of the quark Dirac operator is known
to consist of localized states. This comes about because around the cross-over
temperature to the quark-gluon plasma, localized states start to appear at the
low end of the spectrum and as the system is further heated, states higher up
in the spectrum also get localized. Since localization and the crossover...
