Using the Floquet formalism, we calculate the net pumped current generated and controlled by the side-gate voltage. The control of the current is achieved by varying the phase shift between the two side-gate voltages as well as the Fermi energy. In particular, the maximum current is reached when the side-gate voltages are in quadrature. This new design based on connected quantum rings controlled without magnetic fields can be easily integrated in standard electronic devices.engjournal articlehttp://dx.doi.org/10.1016/j.physleta.2014.06.037http://www.sciencedirect.com/open access538.9PotentialsFluxFísica de materiales
