Scaling configurational entropy, activation energy and relaxation time plots. (a) Experimental evolution of the normalized configurational entropy as a function of the dimensionless temperature TN/T for the tested materials. Solid lines indicate the analytical evolution of the normalized configurational entropy computed taking into account the divergence temperature TN and the order parameter n for each tested material. The analytical representation of the normalized configurational entropy for the case of n = 1 is also shown. (b–d) Normalized configurational entropy, activation energy and relaxation time derived from the model-free route as a function of the dimensionless temperature for the tested materials. (e) Schematic representation of the relation between the physical magnitudes and the dynamics of the system.
