Abstract

The mean-squared voltage fluctuation of a disordered conductor of lengthL smaller than the phase coherence lengthLϕ, is independent of the distance between the probes. We obtain this result using the voltage additivity and the known results for the conductance fluctuation. Our results complement the recent theoretical and experimental findings.
