摘要
The frequency dependence of ionic conductivity sigma(omega) in a one-dimensional hopping-model system is investigated by means of the pair-approximation of the path probability method (PPM) and the Monte Carlo simulation (MCS), where the MCS-method in calculating sigma(omega) is developed. Comparative study of the two methods elucidates that the PPM correctly reproduces sigma(omega) obtained by the MCS in the case of non-interacting ions, but it deviates in the case of strongly interacting ions.
