Slowing Down Mechanisms

Abstract

The basic phenomenon of the dynamic glass transition is the more or less continuous slowing down of the relevant molecular motion as expressed for example by increasing viscosity for falling temperatures (Sect. 2.1.1) or by the declining traces of different processes in the Arrhenius diagram (e.g., a, β, α and ø in Fig. 2.32). These processes were described in Chap. 2, building up to a preliminary physical picture in Sect. 2.5.3. A series of phenomenological concepts was discussed in Chap. 3. Nonconventional aspects were included since I think that the cooperative α process and the ultraslow ø Fischer modes cannot be explained by conventional theories of liquid dynamics. The aim of the present chapter is to illustrate mathematical structures that could reflect the slowing down.
