Scaling for relaxation rates spectra and local configurational entropy in the hierarchically constrained dynamic model of glassy relaxation

Abstract

Within the framework of the hierarchically constrained dynamic model for glassy relaxation we have a procedure that allows us to reduce the relaxation rates spectra of a glass-forming system for different temperatures onto a single universal curve. This procedure is valid in a wide temperature region where the simple approximation of time-temperature scaling is violated. A connection of a natural variable of this universal curve with the local configurational entropy has been examined.
