Transport through driven nanoscale conductors
- We consider the electron transport through driven tight-binding systems. For the theoretical description, a Floquet scattering approach and a Floquet master equation approach are derived. Both formalisms are particularly suited for the exact treatment of non-adiabatic driving. While the scattering approach describes coherent transport exactly, the master equation approach is suitable for a rather direct extension to the case of electron-phonon interaction. Moreover, we derive an expression for the corresponding transport noise which in the driven case depends on the phases of the transmission amplitudes. With these formalisms, we study different situations like the transport through driven molecular wires, the dynamics of coherent quantum ratchets, and the control of current and noise by ac fields.
