Abstract

Recent experimental studies of electrical conduction in a specially prepared silver-based material, across which a spark has been passed, are interpreted through electrical conduction via charge density waves (CDWs) moving in a dc electric field along quasi-one-dimensional chains of Ag+-ions inside the branches of the discharge pattern engraved in the material by the spark. Here we present experimental evidence that the resistance along a number N of branches connected in parallel increases in quantized steps of height $h/2e^{2}N$ with increasing voltage applied across the branches
