Stretched Times and Divergent Time Scales Near the Glass Transition

Even though the mechanical properties differ greatly, not much seems to change between particle positions as a liquid transforms into a glass. However, interesting physics is occurring. For example, experiments reveal a stretched exponential decay of dielectric relaxation with a time scale that diverges at a critical temperature Tc (below the glass transition temperature Tg). A thermodynamics and kinetics theory based on defect motion and clustering is presented to explain glass transition phenomena. The inclusion of pressure effects allows the calculation of quantities such as ionic conductivity near Tg as a function of pressure.
