Corresponding states of structural glass formers. II.
The earlier paper of this same title demonstrated a collapse of relaxation data of fragile supercooled glass forming liquids [J. Phys. Chem. B 2009, 113, 5563-5567]. For temperature T below that of the onset to supercooled behavior, T(o), the logarithm of structural relaxation time, log τ, is given by the parabolic form log(τ/τ(o)) = J(2)(1/T - 1/T(o))(2), where J and τ(o) are temperature-indep...
متن کاملCorresponding states of structural glass formers.
The variation with respect to temperature T of transport properties of 58 fragile structural glass-forming liquids (67 data sets in total) are analyzed and shown to exhibit a remarkable degree of universality. In particular, super-Arrhenius behaviors of all supercooled liquids appear to collapse to one parabola for which there is no singular behavior at any finite temperature. This behavior is ...
متن کاملDynamic order-disorder in atomistic models of structural glass formers.
The glass transition is the freezing of a liquid into a solid state without evident structural order. Although glassy materials are well characterized experimentally, the existence of a phase transition into the glass state remains controversial. Here, we present numerical evidence for the existence of a novel first-order dynamical phase transition in atomistic models of structural glass former...
متن کاملCoarse-grained microscopic model of glass formers.
We introduce a coarse-grained model for atomic glass formers. Its elements are physically motivated local microscopic dynamical rules parameterized by observables. Results of the model are established and used to interpret the measured behaviors of supercooled fluids approaching glass transitions. The model predicts the presence of a crossover from hierarchical super-Arrhenius dynamics at short...
متن کاملSpontaneous and induced dynamic correlations in glass formers. II. Model calculations and comparison to numerical simulations.
We study in detail the predictions of various theoretical approaches, in particular, mode-coupling theory (MCT) and kinetically constrained models (KCMs), concerning the time, temperature, and wave vector dependence of multipoint correlation functions that quantify the strength of both induced and spontaneous dynamical fluctuations. We also discuss the precise predictions of MCT concerning the ...
