FIG. 1.

Driven TDQS where oscillating tunneling barriers between the central quantum dot and its neighbors are considered. The system is driven by an ac potential and the left and right tunneling barriers are rigidly coupled to the leads.

(a) (in units of ) vs (blue solid line) for the ac parameters , and , and typical values of the parameters . The red dashed line corresponds to in the undriven case. The ac current peaks are labeled with , and , associated to the sum rules given by Eqs. (2) and (3), respectively. In (b) we show the occupation probabilities of the right dot , for (green line), (red dashed line), and (blue dotted line), as a function of time, corresponding to the current peak at .
