Figure 2

(a) Rescaled Arrhenius plot of the relaxation time . The symbols represent the simulated data and the dashed line illustrates its high temperature Arrhenius behaviour. Above T≈0.6, conforms to Arrhenius behaviour. (b) Estimation of TA using the logarithmic derivative of the mean-square displacement (equation (7)). For T ≳ 0.6, ∂ ln ‹r2(t)›/∂ ln t has no local minimum near 1 ps. The inset illustrates the time dependence of ‹r2(t)›. The colour gradient of the lines represents the range of temperatures simulated.
