On Static and Dynamic Heterogeneities in Water

الأصل · EN

We analyze differences in dynamics and in properties of the sampled potential energy landscape between different equilibrium trajectories, for a system of rigid water molecules interacting with a two body potential. On entering in the supercooled region, differences between different realizations enhance and survive even when particles have diffused several time their average distance. We observe a strong correlation between the mean square displacement of the individual trajectories and the average energy of the sampled landscape.
