Abstract

Many of the interesting effects in mesoscopic systems are quantum interference phenomena. Such are, e.g., the weak localization corrections to the conductivity, the universal conductance fluctuations, persistent currents and many others. Those effects are known to be affected by the coupling of the interfering particle to its environment, e.g., to a heat bath. The way such a coupling affects quantum phenomena has been studied for a long time, both theoretically [1,2], and experimentally. The effect of the coupling to the environment is characterized by the “phase-breaking” time, τϕ.
