Abstract
Kincs and Martin [Phys. Rev. Lett. 76, 70 (1996)] have recently discov ered a ubiquitous non-Arrhenius temperature dependence of the ionic co nductivity in glassy fast ionic conductors when the conductivity excee ds the high level of 10(-3) to 10(-2) Omega(-1) cm(-1). This important experimental discovery is readily explained and reproduced quantitati vely by the coupling scheme without the use of any adjustable paramete r.
