Shot noise in the interacting resonance level model
arXiv:0706.4003 · doi:10.1103/PhysRevB.76.193307
Abstract
The shot noise power and the Fano factor of a spinless resonant level model is calculated. The Coulomb interaction which in this model acts between the lead electron and the impurity is considered in the first order approximation. The logarithmic divergencies which appeared in the expressions for shot noise and the transport current are removed by renormalization group analysis. It is shown that Keldysh technique gives an adequate description of perturbation theory results. By passing to the bosonized form of the resonance model it is proven that in the strong interaction limit the tunnelling becomes irrelevant and decreases.
