Abstract

We examine the statistics of current fluctuations in a junction with a quantum dot described by Kondo Hamiltonian. With the help of modified Keldysh technique we calculate the third current cumulant S₃. As a function of applied bias S₃ was obtained in three different regimes: Fermi liquid regime, crossover region and RG limit. Third cumulant shows strong non-linear voltage dependence. Only in the asymptotical limit its linear dependence on V is recovered.
