Shot noise near the unitary limit of a Kondo quantum dot
A. Golub
Abstract
We examine the statistics of current fluctuations in a junction with a quantum dot described by Kondo Hamiltonian. With the help of Keldysh technique we calculate shot noise as a function of applied voltage at zero temperature using the fix-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.
