Abstract

Conductance fluctuations in the mesoscopic systems are studied from diffusive to ballistic regimes. It is shown that the conductance fluctuations are enhanced in the presence of the independent current-carrying states and/or independently fluctuating spatial domains not only in the diffusive but also near the ballistic regimes.
