## Abstract In this work, we study the effect of an applied ac gate voltage on the spin filtering and pumping properties of a lateral double quantum dot, in the Coulomb blockade and weak coupling regimes, considering not only the effect of the ac potential on the interβdot tunneling but also on the

We describe photon assisted tunneling (PAT) in single and coupled quantum dot systems which have a relatively large zero-dimensional (0D) level separation. A microwave electric field applied across the tunneling barrier leads to the formation of a sideband structure. For a single quantum dot system,
In a numerical simulation we demonstrate spin readout by using photon assisted tunneling (PAT). We are using a realistic double quantum dot design including a micro-magnet. The micro-magnet generates different Zeeman fields between the two dots. If the photon frequency matches the energy difference
