THEORETICAL BACKGROUND OF THE LIQUID-LIKE MODEL OF SUPERIONIC CONDUCTORS

A statistical mechanical basis is given to the liquid-like model of superionic conductors which has been proposed recently by the authors. It is shown that the heavy ion mass introduced ad hoc in the previous reports to characterize the immobile lattice ions, is related to the mean square displacement of the lattice ion and to the coarse graining time which appears in the time averaging operation. The idea underlining in the liquid-like model, objective, immediate application and further direction are also discussed. © 1990, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
