Features of SU(N) Gauge Theories
B. Lucini, M. Teper, U. Wenger
We review recent lattice results for the large limit of SU(N) gauge theories. In particular, we focus on glueball masses, topology and its relation to chiral symmetry breaking…
Z2 monopoles in D=2+1 SU(2) lattice gauge theory
A. Hart, B. Lucini, Z. Schram +1
We calculate the Euclidean action of a pair of Z2 monopoles (instantons), as a function of their spatial separation, in D=2+1 SU(2) lattice gauge theory. We do so both above and be…
The topological susceptibility and pion decay constant from lattice QCD
UKQCD Collaboration, A. Hart, M. Teper
We study the topological susceptibility, chi, in two flavour lattice QCD. We find clear evidence for the expected suppression of chi at small quark mass. The estimate of the pion d…
On the spectral density from instantons in quenched QCD
U. Sharan, M. Teper
We investigate the contribution of instantons to the eigenvalue spectrum of the Dirac operator in quenched QCD. The instanton configurations that we use have been derived, elsewher…
The string tension in the maximally Abelian gauge after smoothing
A. Hart, J. D. Stack, M. Teper
We apply smoothing to SU(2) lattice field configurations in 3+1 dimensions before fixing to the maximally Abelian gauge. The Abelian projected string tension is shown to be stable…
Topological Structure of the SU(3) Vacuum
Douglas A. Smith, Michael J. Teper
We investigate the topological structure of the vacuum in SU(3) lattice gauge theory. We use under-relaxed cooling to remove the high-frequency fluctuations and a variety of "filte…
Monopole clusters in Abelian projected gauge theories
A. Hart, M. Teper
We show that the monopole currents which one obtains in the maximally Abelian gauge of SU(2) fall into two quite distinct classes (when the volume is large enough). In each field c…
Magnetic monopole clusters, and monopole dominance after smoothing in the maximally Abelian gauge of SU(2)
A. Hart, M. Teper
In the maximally Abelian gauge of SU(2), the clusters of monopole current are found to divide into two distinct classes. The largest cluster permeates the lattice, has a density th…
Monopole Spectra in non-Abelian Gauge Theories
A. Hart, M. Teper
We study the continuum limit of the length spectrum of magnetic monopole structures found after various Abelian projections of pure gauge SU(2), including the maximally Abelian gau…
Domain walls and perturbation theory in high temperature gauge theory: SU(2) in 2+1 dimensions
C. Korthals Altes, A. Michels, M. Stephanov +1
We study the detailed properties of Z_2 domain walls in the deconfined high temperature phase of the d=2+1 SU(2) gauge theory. These walls are studied both by computer simulations…
Gribov Copies in the Maximally Abelian Gauge and Confinement
A. Hart, M. Teper
We fix lattice gauge fields to the Maximally Abelian gauge in both three and four dimensions. We extract the corresponding fields and monopole current densities and…
Instantons and Monopoles in the Maximally Abelian Gauge
A. Hart, M. Teper
We study the Abelian projection of SU(2) instantons in the Maximally Abelian gauge. We find that in this gauge an isolated instanton produces a closed monopole loop within its core…
