The vacuum type of SU(2) gluodynamics is studied using Monte-Carlosimulations in maximally Abelian (MA) gauge and in Landau (LA) gauge, where thedual Meissner effect is observed to work. The dual Meissner effect ischaracterized by the coherence and the penetration lengths. Correlationsbetween Wilson loops and electric fields are evaluated in order to measure thepenetration length in both gauges. The coherence length is shown to be fixed inthe MA gauge from measurements of the monopole density around the staticquark-antiquark pair. It is also shown numerically that a dimension 2 gluonoperator A^+A^-(s) and the monopole density has a strong correlation assuggested theoretically. Such a correlation is observed also between themonopole density and A^2(s)= A^+A^-(s) + A^3A^3(s) condensate if the remainingU(1) gauge degree of freedom is fixed to U(1) Landau gauge (U1LA). Thecoherence length is determined numerically also from correlations betweenWilson loops and A^+A^-(s) and A^2(s) in MA + U1LA gauge. Assuming that thesame physics works in the LA gauge, we determine the coherence length fromcorrelations between Wilson loops and A^2(s). Penetration lengths and coherencelengths in the two gauges are almost the same. The vacuum type of theconfinement phase in both gauges is near to the border between the type 1 andthe type 2 dual superconductors.Comment: 13 pages, 22 figures, RevTeX 4 styl
