Abstract
Various problems and limitations of a recent Coulomb-fluctuation model by Bondarev and Pikhitsa [Phys. Lett. A 196 (1994) 247] for the trans ient and frequency response of disordered conductors are considered. T he model can be expressed in terms of a simple Gaussian distribution o f activation energies, contains an inconsistency, and is of much less general applicability than is claimed by its authors.
