Deconfining by winding: The magnetic monopole vacua at high temperatures -art. no. 105021

Characterizing the vacuum of a thermalized SU(3) Yang-Mills theory in the d ual Ginzburg-Landau description, the possibility of topologically nontrivia l, classical monopole fields in the deconfining phase is explored. These fi elds are assumed to be Bogomol'nyi-Prasad-Sommerfield saturated solutions a long the compact, Euclidean time dimension. A corresponding, gauge invarian t monopole interaction is constructed. The model passes first tests. In par ticular, a reasonable value for the critical temperature is obtained, and t he partial persistence of nonperturbative features in the deconfining phase of SU(3) Yang-Mills theory, as it is measured on the lattice, follows natu rally.
