Turbulent thermalization of weakly coupled non-Abelian plasmas

We study the dynamics of weakly coupled non-Abelian plasmas within the frameworks of classical-statistical lattice gauge theory and kinetic theory. We focus on a class of systems which are highly occupied, isotropic at all times and initially characterized by a single momentum scale. These represent an idealized version of the situation in relativistic heavy-ion collisions in the color glass condensate picture, where on a time scale 1/Q(s) after the collision of heavy nuclei a longitudinally expanding plasma characterized by the saturation scale Q(s) is formed. Our results indicate that the system evolves according to a turbulent Kolmogorov cascade in the classical regime. Taking this into account, the kinetic description is able to reproduce characteristic features of the evolution correctly.
