Ultrafast spin-dependent dynamics and high harmonic generation in semiconductor nanostructures — •Dominik Schulze and Jamal Berakdar — Institute of Physics, Martin-Luther-University Halle-Wittenberg, 06099 Halle/Saale, Germany

Using a direct time propagation technique, we investigate the time-resolved charge and spin quantum dynamics of semiconductor based heterostructures subjected to ultrashort laser pulses. Special attention is devoted to effects related to spin-orbital coupling. It is shown how the time and polarization-resolved emission spectrum can be controlled via the parameters of the driving field as well as by nanostructuring. It is pointed out how the footprints of the spin dynamics can be traced via monitoring in the emission spectrum.
