dc.descriptionThe utility of a cooperative length scale for describing the dynamics of glass-forming liquids is shown using literature data on o-terphenyl. Molecular dynamics and Monte Carlo simulations reveal a distribution of cooperative fractal events below the caging temperature T_A. Guided by these results, we show how to extract the size of slow regions in any glass-forming liquid from probe rotation/diffusion measurements, which agrees quantitatively with 4-D NMR and grows steadily as temperature is lowered below T_A. We clarify why this length must also be the size of the largest cooperative events.
