摘要：We report on a recent calculation of the time evolution of Polyakov loop fluctuations from a
simple classical relativistic Lagrangian after a quench into the deconfined phase of SU(3) gauge
theory. The structure factors indicate spinodal phase conversion followed by relaxation, similarly
to results obtained via Markov Chain Monte Carlo techniques in SU(3) lattice gauge theory. The
time for which the structure factor reaches its maximum diverges in the long-wavelength limit
due to formation of non-perturbatively large competing Z(3) Polyakov loop domains, which delay
thermalization of long wavelength modes. For realistic temperatures, and away from the extreme
weak-coupling limit, also modes with k on the order of T experience delayed thermalization. As
relaxation times of very long wavelength modes are found to be on the order of the size of the
system, the dynamics of competing domains should accompany the hydrodynamic description of
the deconfined vacuum.
