Holographic thermalization in [Formula: see text] super Yang–Mills theory at finite coupling

We investigate the behavior of energy-momentum tensor correlators in holographic [Formula: see text] super Yang–Mills plasma, taking finite coupling corrections into account. In the thermal limit we determine the flow of quasinormal modes as a function of the ’t Hooft coupling. Then we use a specifi...

Sumario:We investigate the behavior of energy-momentum tensor correlators in holographic [Formula: see text] super Yang–Mills plasma, taking finite coupling corrections into account. In the thermal limit we determine the flow of 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 densities from their 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 the weakening of the usual top-down thermalization pattern.
