摘要：We show that the degrees of freedom associated with magnetic monopole– and vortexlike gluonic configurations make a strong contribution to the anomaly of the energy–momentum tensor of Yang–Mills theory in the deconfinement phase immediately above the critical temperature. As is well known in zero–temperature Yang–Mills theory, the monopoles and vortices are constituents of a generic gluonic object in which the two neighbor monopoles are connected together by a segment of vortex string. Our results provide evidence that the monopole-vortex chains in SU(2) gauge theory and their SU(3) counterparts, the monopole-vortex nets, are thermodynamically relevant degrees of freedom in the gluonic plasma.
