Non-equilibrium shot noise (a), as well as Fano factor (b), calculated as a function of the bias voltage for S = 5/2. Parameters: ε 0 = 2, J = 1, Γ L = Γ R = 0.01, and zero temperature. Inset: Fano factor for single-channel model with parameters ε 0 = 1 and Γ L = Γ R = 0.1. Energy unit is given in the half-bandwidth D .
