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…

Lattice Fermions without Doublers
Kevin Cahill
By placing fermions only on the even sites of a lattice, one may halve the momentum spectrum and construct a theory without doublers. The interaction is nonlocal. The fermion propa…

Noncompact Gauge-Invariant Lattice Simulations
Kevin Cahill, Gary Herling
We have applied a new gauge-invariant, noncompact, Monte Carlo method to simulate , , and gauge theories on and lattices. The Creutz ratios of the…
