Backward correlations and dynamic heterogeneities: A computer study of ion dynamics
We analyze the correlated back and forth dynamics and dynamic heterogeneities, i.e., the presence of fast and slow ions, for a lithium metasilicate system via computer simulations. For this purpose we define, in analogy to previous work in the field of glass transition, appropriate three-time correlation functions. They contain information …
