Abstract
The time-dependent charge transfer between quantum dots induced by an ultrashort electric field is theoretically analyzed. For double quantum dot coupled to metallic reservoirs we show that the electron-tunneling processes are analogous to those occurring in collisions between ions and atoms. As a consequence, the total current exhibits Stuckelberg-like oscillations as a function of the duration and amplitude of the external field. This effect leads to a remarkable enhancement of the nonlinear response.
