Quantum tunneling through moving Kondo objects

We show how the time-dependent modulation of charge input signal applied to the gate electrode in a double quantum dot may be converted to a pulse in the Kondo tunneling current, which is predominantly spin response of this nano-device in a strong Coulomb blockade regime. The stochastic component of the input signal reveals itself as the infrared cutoff of Kondo tunneling transmission (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
