| contents | We extract the complex frequency of the lowest quasi-normal mode from the holographically computed entropy density near thermodynamic equilibrium. The system consists of a purely thermal Supersymmetric Yang-Mills N=4 plasma in homogeneous isotropization dynamics. The initial state is far-from-equilibrium, proceeding to thermalization over time. The system evolves to equilibrium entropy forming a stairway pattern. The analysis reveals that the rate of increase of the stairway is twice the decay rate of the lowest quasi-normal mode. This leads us to propose a model explaining how this information is encoded in entropy. The model is extended to consider finite temperature, R-charge density and scalar condensate of the medium, disclosing an additional feature. The system's main dissipation channel may shift to one driven by the scalar condensate, depending on the chemical potential. |
