We are participating in the trans-regional collaborative research center TRR227. 18 projects located at the Freie Universität Berlin, the Martin-Luther-Universität Halle-Wittenberg, the Helmholtz-Zentrum Berlin, the Max-Born-Institut and the Fritz-Haber-Institut will study ultrafast spin dynamics with different approaches. We will use trARPES for the investigation of charge and spin currents in heterostructures. A project summary can be found here.
