We compute nonequilibrium dynamics for classical-statistical SU(2) pure gauge theory on a lattice. We consider anisotropic initial conditions with high occupation numbers in the transverse plane on a characteristic scale ∼ Q s. This is used to investigate the very early stages of the thermal-ization process in the context of heavy-ion collisions. We find… (More)

We compute nonequilibrium dynamics of plasma instabilities in classical-statistical lattice gauge theory in 3+1 dimensions. The simulations are done for the first time for the SU(3) gauge group relevant for quantum chromo-dynamics. We find a qualitatively similar behavior as compared to earlier investigations in SU(2) gauge theory. The characteristic growth… (More)

We study the phase structure of a 4D complex scalar field theory with a potential V (Φ) = | Λ 3 Φ − ΛΦ | 2 at zero and at finite temperature. The model is analyzed by mean-field and Monte Carlo methods. At zero temperature the theory falls in the universality class of the 4D Ising model when varying Λ. The situation is less clear-cut for variations w.r.t. Λ… (More)
