A unified theory for the glass transition singularities(Session III : Complex Fluids, The 1st Tohwa University International Meeting on Statistical Physics Theories, Experiments and Computer Simulations)

Abstract

A unified view for the glass transition singularities is given on the basis of a heuristic argument for the elementary relaxtion process. Three predictions are made : (i) the Kauzmann temperature T_K is eqaul to the Vogel-Fulcher temperature T_<VF>, and the glass transition temerature T_g satisfies (ii) T_gs_C(T_g)～constant and (iii) T_xs_C(T_x)/T_gs_C(T_g)=2, where T_x is the crossover temperature and s_C(T) is the excess entropy per molecule.
