Anomalous Conductance Distribution in Quasi-One-Dimensional Gold Wires: Possible Violation of the One-Parameter Scaling Hypothesis

摘要

Mohanty and Webb claim that their data on conductance fluctuations in gold wires contradict the one-parameter scaling. We show that flaws in extracting values of the cumulants g~n of the conductance distribution (for n = 3, 4) invalidate their conclusions. The true values of g~n determined by us from the raw data published in Ref. are orders of magnitude smaller than those claimed and are within a systematic error due to the limited applicability of the ergodicity hypothesis.
