Contributions and for each site in system LS-2.
Correlation among the energies of neighboring sites in system LS-2.
Growth of the standard deviation of energies for a site with sampling time. The behavior of is similar to that for .
Development of the energy of an ion directly after the jump into a site at . Three sets of residences with different durations are distinguished, designated short, medium, and long. Behavior at the end of a residence before the jump is equivalent.
Mean relative occupation of the sites in LS-2 plotted against . The solid line is a Fermi–Dirac function with , the open symbols were generated from a Monte Carlo model that recreates the MD system (see text).
Mean residence times plotted against the site energies and .
Comparison of the probability for the ion population of site in a simple vacancy model (see text) with its Fermi estimate. In one case (circles) the ion-ion interaction does not depend on the position of the vacancy, in the other case (squares) a weak dependence has been taken into account (see text for details).
Gaussian fits for the distribution of site energies .
