Holographic thermalization at intermediate coupling

I will review some progress made recently in the description of the thermalization process in heavy ion collisions, using strongly, but not infinitely strongly coupled N=4 Super Yang-Mills theory as a toy model. Special attention will be paid to the determination of out-of-equilibrium Green's functions of the energy momentum tensor and an external U(1) gauge field, as well as to the pattern with which these quantities approach their respective thermal limits. Based on the results, I will argue that the usual top/down pattern of holographic thermalization weakens signicantly, as one leaves the limit of infinite coupling.
