Résumé :
Confinement in non-Abelian gauge theories is commonly ascribed to percolation of magnetic monopoles, or strings in the vacuum. At the deconfinement phase transition the condensed magnetic degrees of freedom are released into gluon plasma as thermal magnetic monopoles. We show that right above the critical temperature the density of monopoles/strings remains a constant function of temperature, as for a liquid, and then grows, like for a gas. New numerical results uncovering strong contribution of the magnetic strings to the trace anomaly in Yang-Mills plasma are also to be reported. Based on paper M.N. Chernodub, V.I. Zakharov, Phys.Rev.Lett.98:082002,2007 [hep-ph/0611228] and also on the talk hep-ph/0702245
