Landau-like theory of glassy dynamics.
An exact solution of a Landau model of an order-disorder transition with activated critical dynamics is presented. The model describes a funnel-shaped topology of the order parameter space in which the number of energy lowering trajectories rapidly diminishes as the ordered ground state is approached. This leads to an asymmetry in the effective transition rates which results in a nonexponential...

متن کاملShear-transformation-zone theory of linear glassy dynamics.
We present a linearized shear-transformation-zone (STZ) theory of glassy dynamics in which the internal STZ transition rates are characterized by a broad distribution of activation barriers. For slowly aging or fully aged systems, the main features of the barrier-height distribution are determined by the effective temperature and other near-equilibrium properties of the configurational degrees ...
متن کاملThe essentials of the mode-coupling theory for glassy dynamics
The essential results of the mode-coupling theory for the evolution of structural relaxation in simple liquids such as the Debye-Waller-factor anomaly, the critical decay, von Schweidler’s law, the α and β -relaxation scaling, the appearance of two divergent time scales, and Kohlrausch’s law for the α -process are explained, and their relevance to the understanding of experiments in glass-formi...
