Thermalization of weakly coupled non-Abelian plasmas

The question how thermalization is achieved in relativistic heavy-ion collision provides one of the biggest theoretical challenges in our current understanding of the experiments performed at RHIC and the LHC. In this talk I address the problem of thermalization of weakly coupled non-abelian plasmas from a more general point, by considering a class of systems which share important features with the one created in relativistic heavy-ion collisions. In the first part of this talk, I discuss the occurrence of Kolmogorov wave turbulence in non-abelian gauge theories which drives the thermalization process in non-expanding plasmas. In the second part of this talk I present preliminary results on the properties of longitudinally expanding plasmas, which are phenomenologically relevant for relativistic heavy-ion collisions. In both cases numerical and analytical considerations are presented.
