摘要：

We developed a theoretical framework which extends the method of full counting statistics (FCS) from conventional single-channel Kondo screening schemes to a multichannel Kondo paradigm. The developed idea of FCS has been demonstrated considering an example of a two-stage Kondo (2SK) model. We analyzed the charge-transferred statistics in the strong-coupling regime of a 2SK model using a nonequilibrium Keldysh formulation. A bounded value of the Fano factor, 1 <= F <= 5/3, confirmed the crossover regimes of charge-transferred statistics in the 2SK effect, from Poissonian to super-Poissonian. An innovative way of measuring the transport properties of the 2SK effect, by the independent measurements of charge current and noise, has been proposed.
