Abstract
Evidence is presented to support the hypothesis that physical systems in thermodynamic nonequilibrium possess, among other fluctuation phenomena, nonstationary noise with a true 1/fα‐power spectral density over all frequencies, and that such spectra are stable. Some consequences of this hypothesis are derived, and a class of time‐dependent autocorrelation functions for such a process is proposed.This publication has 11 references indexed in Scilit:
