We investigate local cooling of gauge field configurations in four-dimensional SU (2) lattice gauge theory. After abelian projection, abelian magnetic monopole current is identified in the cooled configurations and is used to compute the string tensi

We present numerical calculations using the magnetic monopoles of four-dimensional U(1) lattice gauge theory to obtain the heavy quark potential. Using the cosine action we perform a conventional gauge field simulation on a 164 lattice. We then use t

We have calculated the static quark potential using the magnetic monopoles of U(1) lattice gauge theory ( LGT ). Our calculations use monopoles which are identified in gauge field configurations generated using the Wilson action. We find that the mon

Calculations are presented which obtain the heavy quark potential using magnetic monopole current variables in U (1) and SU (2) lattice gauge theory. Very large loops of magnetic current are found in simulations of both theories. In the U (1) theory,

Almost all lattice work on confinement has been carried out for an SU (2) gauge group. This is a good starting point. Confinement is caused by glue and every physicist believes that there is no essential physical difference in the confining propertie

We present results for the heavy quark potential computed in SU(3) from magnetic monopoles and from center vortices. The monopoles are identified after fixing SU(3) lattice configurations to the maximal abelian gauge. The center vortices are identifi

We present results suggesting that magnetic monopoles can account for chiral symmetry breaking in abelian gauge theory. Full U(1) configurations from a lattice simulation are factorized into magnetic monopole and photon contributions. The expectation

In the quenched approximation we use the abelian and monopole fields from abelian projection in SU(2) lattice gauge theory to numerically compute the value of the chiral condensate. The condensate calculated using abelian projection is observed to va

We resolve a discrepancy between the SU(2) spacial string tension at finite temperature, and the value obtained by monopoles in the maximum Abelian gauge. Previous work had incorrectly omitted a term due to Dirac sheets. When this term is included, t
