چکیده
We review the confinement scenario in Coulomb gauge. We show that when thin center vortex configurations are gauge transformed to Coulomb gauge, they lie on the common boundary of the fundamental modular region and the Gribov region. This unifies elements of the Gribov confinement scenario in Coulomb gauge and the center-vortex confinement scenario. We report on recent numerical studies which support both of these scenarios.

We consider numerical data for the lattice Landau gluon propagator obtained at very large lattice volumes in three-dimensional pure SU(2) Yang-Mills gauge theory (YM 2 3). We find that the temporal correlator C(t) shows an oscillatory pattern and is negative for several values of t. This is an explicit violation of reflection positivity and can be related to gluon confinement. We also obtain a ...

Lattice simulations are presented showing the expectation of the fluctuation of the Wilson loop solely by elements of the center to fully reproduce the SU(3) heavy quark potential. The results are stable under smoothing, and point to thick vortices as being responsible for the full SU(3) tension. An analytic result on the necessary presence of thick vortices for confinement at weak coupling is ...

We present numerical evidence that supports the theory of quark confinement based on center vortex condensation. We introduce a special gauge (“maximal center gauge”) and center projection, suitable for identification of center vortices. Main focus is then put on the connection of vortices in center projection to “confiners” in full, unprojected gauge-field configurations. Topics briefly discus...

We discuss theories with the exceptional centerless gauge group G(2), paying attention to confinement and the pattern of chiral symmetry breaking. Exploiting the Higgs mechanism to break the symmetry down to SU (3), we also present how the familiar features of confinement and chiral symmetry breaking of SU (3) gauge theories reemerge. G(2) gauge theories show up as an unusual theoretical framew...

Large center vortices and confinement in 3D Z 2 gauge theory. Abstract We study the role of large clusters of center vortices in producing confinement in 3D Z2 gauge theory. First, we modify each configuration of a Monte Carlo-generated ensemble in the confined phase by removing the largest cluster of center vortices, and show that the ensemble thus obtained does not confine. Conversely, we sho...
