Ultrafast photo-induced spin polarized currents in nanostructers — •Michael Kraus, Dominik Schulze, Anna Dyrdal, and Jamal Berakdar — Martin-Luther Universität Halle-Wittenberg

We present theoretical predictions on the ultrafast generation of spin-polarized currents and pure spin currents by an appropriate nanostructuring of the sample and/or by modulating local fields produced by nearby plasmonic elements. It is shown how spin currents are steered by spatio-temporal tailoring of the driving photonic fields.
