This is due to the fact that the Wiedemann-Franz law is no longer valid in the case of considerable electron-electron interaction. The deviations from this law increase the noise power and make it dependent strongly on the ratio of electron-electron and electron-impurity scattering rates.4 pages, 2 figures, revised version according to referee's commentsMesoscale and Nanoscale Physicstext
