Abstract
A Monte Carlo simulation method for the calculation of the frequency-dependent electrical conductivity and the associated time correlation function is illustrated for a two sublattice vacancy migration model, and some discrepancies with current kinetic theories are observed. The method should be of wide utility for atom hopping models in determining the frequency dependence of transport coefficients and in the calculation of time correlation functions which provide additional tests of kinetic theories of both the static and the frequency-dependent transport coefficients.
