Chiral Symmetry and Quark Confinement
Kevin Cahill
In the physical vacuum of QCD, the energy density of light-quark fields strongly coupled to slowly varying gluon fields can be negative, and so a condensate of pairs of quarks and…

Confinement Artifacts in the U(1) and SU(2) Compact Lattice Gauge Theories
Kevin Cahill, Gary Herling
We identify the artifact that causes confinement at strong coupling in compact U(1) lattice gauge theory and show that most of the string tension in compact SU(2) lattice gauge the…
