Fig. 5: Scaled plot for shear-rate dependence of the relaxation time in the Gaussian core model (GCM).

\({\tau }_{\alpha }(T,\dot{\gamma })/{\tau }_{\alpha 0}(T)\) is plotted as a function of \(\dot{\gamma }/{\dot{\gamma }}_{c}\). Symbols of different colors represent values at different T; T × 106 = 10.0 (yellow), 7.0 (purple), 5.0 (green), 4.0 (cyan), 3.4 (orange), 3.2 (blue), 3.0 (red), and 2.9 (black). Black and blue lines indicate τα/τα0 = 1 and \({\tau }_{\alpha }/{\tau }_{\alpha 0}\propto {(\dot{\gamma }/{\dot{\gamma }}_{c})}^{-\nu }\) with ν ≃ 0.73, respectively. The vertical dotted line indicates the location of the onset shear rate \({\dot{\gamma }}_{c}\).
