Flow curves of the model, viz, dimensionless stress vs , for two states that would be fluid, respectively, glassy without shear; and (where ). Straight lines with slope unity indicate the variation following the low shear and high shear viscosity . The inset shows the correlators of the schematic model as function of rescaled time . The curve marked with a relaxation time taken at corresponds to a fluid state without shear (, ). The curve marked by the long-time plateau value corresponds to a glass state without shear (, ). For increasing shear rates, as labeled, the correlators decay more quickly at either value of .
Flow curves, viz, stationary transverse stress as function of shear rate , for the thermosensitive lattices close to glassy arrest at various temperatures from top to bottom as denoted. The temperatures may be thought to correspond to different effective packing fractions.
Stress data from Fig. 2 rescaled by to agree at high shear rate in order to eliminate corrections from i.a. hydrodynamic interactions; rescaling values from top to bottom as indicated in the legend. Solid lines give fits with the schematic model to the flow curves at small where the structural dynamics dominates. The parameters are , , for all curves, and separation parameters as given in Table I. The glass transition temperature lies close to .
Viscosity data and corresponding schematic model fits taken from Fig. 3. The second Newtonian plateau in the fit curves increases with lowering temperature because of the rescaling factors . Curves from top to bottom as labeled.
Parameters, and , for the fits of the flow curves in Fig. 3 using the model. The viscosities and are calculated from the fits using .
