Abstract

The process of environmental decoherence is seen to occur when we include the quantum dynamics of a system and its environment: the innovative idea is that environmental degrees of freedom are relevant even though the coupling to them is only weak. The effect of vacuum fluctuations on electron coherence is known: the time-varying electro-magnetic field produces a time-varying Aharonov-Bohm phase. But it is known too that a conducting boundary modifies the properties of the zero-point fluctuations which, introducing a random stress, affect the electronic transport properties in a carbon nanotube via interaction with a random potentials (impurities) long the tube. We shall discuss the situation in which a quantum-mechanical system, the ballistic electrons in nanotube, is disturbed not just by a classical system but another quantum-mechanical system, the vacuum fluctuations due to conducting boundary , about which there are statistical uncertainties.
