Instanton, Monopole and Confinement
We study the correlation between instantons and QCD-monopoles both in the lattice gauge theory and in the multi-instanton system using the maximally abelian gauge. First, we find the existence of an almost linear correlation between the total length of monopole trajectories and the total number of pseudoparticles (instantons and anti-instantons) in the 16 × 4 SU(2) lattice. Second, we study the...
متن کاملInstanton, Monopole Condensation and Confinement
The confinement mechanism in the nonperturbative QCD is studied in terms of topological excitation as QCDmonopoles and instantons. In the ’t Hooft abelian gauge, QCD is reduced into an abelian gauge theory with monopoles, and the QCD vacuum can be regarded as the dual superconductor with monopole condensation, which leads to the dual Higgs mechanism. The monopole-current theory extracted from Q...

We study color confinement properties of the multi-instanton system, which is assumed to carry the essence of the nonperturbative QCD vacuum. We also investigate the feature of monopoles by taking the maximally abelian gauge considering the correspondence between the monopole and the instanton. The feature of monopole trajectories changes drastically with the instanton density. At the high inst...
متن کاملDistribution of Instanton and Monopole Clustering
We study the relation between the instanton distribution and the monopole loop length in the SU(2) gauge theory with the abelian gauge fixing. We measure the monopole current from the multiinstanton ensemble on the 16 lattice using the maximally abelian gauge. When the instanton density is dilute, there appear only small monopole loops. On the other hand, in the dense case, there appears one ve...

We study color confinement properties of the multi-instanton system, which seems to carry an essence of the nonperturbative QCD vacuum. Here we assume that the multi-instanton system is characterized by the infrared suppression of instantons as f (ρ) ∼ ρ −5 for large size ρ. We first investigate a monopole-clustering appearing in the maximally abelian (MA) gauge by considering the correspondenc...
