SCALING FOR RELAXATION RATES SPECTRA AND LOCAL CONFIGURATIONAL ENTROPY IN THE HIERARCHICALLY CONSTRAINED DYNAMIC-MODEL OF GLASSY RELAXATION

Within the framework of the hierarchically constrained dynamic model f or glassy relaxation we have a procedure that allows us to reduce the relaxation rates spectra of a glass-forming system for different tempe ratures onto a single universal curve. This procedure is valid in a wi de temperature region where the simple approximation of time-temperatu re scaling is violated. A connection of a natural variable of this uni versal curve with the local configurational entropy has been examined. Copyright (C) 1997 Elsevier Science Ltd
