Spin-orbit induced dynamics in a driven single molecule junction — •Moritz Frankerl, Milena Grifoni, and Andrea Donarini — Institut für Theoretische Physik, Universität Regensburg, 93035 Regensburg, Germany

Recent experiments based on THz-STM have shown how to obtain both space and time resolution of molecular dynamics on its intrinsic length and time scales [1]. The average transmitted charge is recorded as a function of tip position and pump-probe pulse delay. We report here on the theoretical investigation of the combined spin and orbital dynamics of a single molecule copper-phthalocyanine junction. The dynamics is studied directly in the time domain, with the full pump-probe scheme simulated within a generalized master equation approach. The spin-orbit coupling on the metallic center is responsible for intertwined spin and orbital dynamics. Control and electrical read out can be achieved respectively via an external magnetic field and coupling to ferromagnetic leads.
