摘要:The dual Meissner effect is described and numerically observed in a gauge-invariant way in lattice
Monte-Carlo simulations in pure SU(2) QCD. The squeezing of the non-Abelian electric field between
a pair of static quark and anti-quark occurs due to the solenoidal current coming from the
gauge-invariant monopole-like quantity. Preliminary results are obtained with respect to the vacuum
type of the confinement phase. The SU(2) QCD vacuum seems near the border between the
type 1 and the type 2 dual superconductors. The theoretical background of this idea is published
in another report [1]. Here we show numerical results in this note.
