Microscopic theory of the steady electrochemical noise near the equilibrium state

In the framework of the quantum theory of irreversible processes, it is sho wn that the microscopic theory of equilibrium noises in electrical multipor ts can be extended almost to the equilibrium state. It is found that the st eady electrical noise near the equilibrium state is determined not only by cross impedances of multiports but also by a set of rectification coefficie nts that characterize nonlinear kinetic features of multiports at equilibri um. The Faraday rectification appears to directly affect changes in the mag nitude and character of the electrochemical noise, caused by the passage of a direct polarization current through the electrochemical cell.
