Fig. 2. Influence of cohesive interaction strength on dynamics of CG model.
The Debye-Waller factor 〈u2〉 versus temperature T for the AA and CG models of PC with varying ER factor α for cohesive interaction strength. The vertical arrow indicates a dataset with increase in α. Inset: The result of α(T) for the CG model determined by preserving the T-dependent 〈u2〉 of the AA model of PC.
