| dc.description | We calculate the charge transfer probability distribution function $χ(λ)$ for the Kondo dot in the strong coupling limit within the framework of the Nozières--Fermi--liquid theory of the Kondo effect. At zero temperature, the ratio of the moments $C_n$ of the charge distribution to the backscattering current $I_{\rm bs}$ follows a universal law $C_n/2I_{\rm bs}=(-1)^n(1+2^n)/6$. The functional form of $χ(λ)$ is consistent with tunnelling of electrons and, possibly, electron pairs. We then discuss the cross-over behaviour of $χ(λ)$ from weak to strong Coulomb repulsion in the underlying Anderson impurity model and relate this to the existing results. Finally, we extend our analysis to the case of finite temperatures. | |
