Super-Arrhenius diffusion in an undercooled binary Lennard-Jones liquid results from a quantifiable correlation effect | | Vanessa K de Souza

10 Feb 2006 | | Journal: | Phys Rev Lett, 96 (5), 057802 | | Abstract: | On short time scales an underlying Arrhenius temperature dependence of the diffusion constant can be extracted from the fragile, super-Arrhenius diffusion of a binary Lennard-Jones mixture. This Arrhenius diffusion is related to the true super-Arrhenius behavior by a factor that depends on the average angle between steps in successive time windows. The correction factor accounts for the fact that on average, successive displacements are negatively correlated, and this effect can therefore be linked directly with the higher apparent activation energy for diffusion at low temperature. | | Source: | PubMed, pmid16486990 | | Services: | Forum | Review | Favorites | |
