“…(19) and (20). While the temporal direction is fixed along the longest side in the 12 3 × 24 lattice, we measure the correlation in all four direction for the symmetric lattices (16 4 and 20 4 ) without fixing the temporal direction. We show in Fig.…”

“…From a phenomenological point of view, quark confinement is characterized by the linear inter-quark potential V (r) ∼ σr with the hadronic string tension σ ≃ 1GeV/fm, which is obtained from the Regge trajectories [1] of hadrons and also from the lattice QCD simulation [2]. This confining force arises from the one-dimensional squeezing of the gluonic flux between the quark and the anti-quark, which is actually observed in the lattice QCD simulation [3].…”

We study effective mass generation of off-diagonal gluons and infrared Abelian dominance in the maximally Abelian ͑MA͒ gauge. Using SU͑2͒ lattice QCD, we investigate the propagator and the effective mass of the gluon field in the MA gauge with U(1) 3 Landau gauge fixing. The Monte Carlo simulation is performed on the 12 3 ϫ24 lattice with 2.2р␤р2.4, and also on the 16 4 and 20 4 lattices with 2.3р␤р2.4. In the MA gauge, the diagonal gluon component A 3 shows long-range propagation, and infrared Abelian dominance is found for the gluon propagator. In the MA gauge, the off-diagonal gluon component A Ϯ behaves as a massive vector boson with the effective mass M off Ӎ1.2 GeV in the region of rտ0.2 fm, and its propagation is limited within a short range. We conjecture that infrared Abelian dominance can be interpreted as infrared inactivity of the offdiagonal gluon due to its large mass generation induced by the MA gauge fixing. ͓S0556-2821͑99͒05223-6͔

The spacial distribution of fields and currents in confining theories can give direct evidence of dual superconductivity. We would like to discuss the techniques for finding these properties and calculating the superconductivity parameters in lattice simulations. We have seen dual Abrikosov vortices directly in pure U(1) and SU(2) and others have also seen them in SU(3). In the non-Abelian cases the system appears to be near the borderline between type I and II. We also discuss the response of the supercurrents to external fields.
