Abstract
We study resonant all-electric adiabatic spin pumping through a quantum dot with two nearby levels by using a Fermi liquid approach in the strongly interacting regime, combined with a projective numerical renormalization group (NRG) theory. Due to spin-orbit coupling, a strong spin pumping resonance emerges at every charging transition, which allows for the transfer of a spin similar to h/2 through the device in a single pumping cycle. Depending on the precise geometry of the device, controlled pure spin pumping is also possible.
