Abstract

A new method that includes long-range interactions is described and used to compute the site-occupancy correlation in a one-dimensional ionic conductor. The method is applied to hollandite, for which the ions move within independent channels. Through this analysis, we deduce specific information about the interionic potential from experimental data on cationic order. Because of the peculiar screening provided by this material, the potential between mobile ions decays quickly for the first few lattice sites and has only a weak Coulomb tail.
