Query: Complete identification of alkali sites in ion conducting lithium
  silicate glasses: a computer study of ion dynamics   The available sites for ions in a typical disordered ionic conductor are
determined. For this purpose we devised a straightforward algorithm which via
cluster analysis identifies these sites from long time ionic trajectories below
the glass transition. This is exemplified for a lithium silicate glass
(Li_2O)_x (SiO_2)_(1-x) for x = 0.5 and x = 0.1. We find for both
concentrations that the number of sites is only slightly bigger than the number
of ions. This result suggests a theoretical description of the dynamics in
terms of mobile vacancies as most appropriate. Furthermore identification of
the ionic sites allows one to obtain detailed characteristics of the ionic
motion, e.g. quantification of correlated forward-backward jumps.
