Abstract
We present detailed theoretical and computer simulation results for the occupancy correlation function associated with particles hopping on a linear chain with two sublattices. In particular, we consider the strongly inequivalent case where one type of site is very much preferred over the other type of site. New normal modes of hopping and a frequency-dependent conductivity are generated by the two-sublattice structure that are not described in the mean-field approximation.Keywords
