摘要：

We examine the statistics of current fluctuations in a junction with a quantum dot described by Kondo Hamiltonian. With the help of Keldysh's technique we calculate shot noise as a function of applied voltage at zero temperature using the fixed-point Hamiltonian. These calculations are complementary to similar ones performed earlier in the mean field slave boson approximation. The results may be relevant for measurement of effective charge carriers.
