Abstract

We investigate the quantum interference induced non-additive contribution to the excess noise due to several mobile scatters in the diffusion/cooperon approximation. For weak impurity coupling and standard assumption on impurity hopping the relative correction to the noise spectrum is proportional to logf. Although the constant of proportionality is small the logarithmic deviation from the main additive part showing 1/f behavior seems rather remarkable.
