Holographic thermalization in N=4 Super Yang-Mills theory at finite

Stefan A. Stricker
We investigate the behavior of the energy momentum tensor correlators in holographic N=4 Super Yang-Mills plasma, taking finite coupling corrections into account. In the thermal limit we determine the flow of the quasinormal modes as a function of the 't Hooft coupling. Then we use a specific model of holographic thermalization to study the deviation of the spectral density from its thermal limit in an out-of-equilibrium situation. The main focus lies on the thermalization pattern with which the plasma constituents approach their thermal distribution as the coupling constant decreases from the infinite coupling limit. All obtained results point towards a weakening of the usual top-down thermalization pattern.
