• How can we write and read magnetic information based on angular momentum as fast as possible?
• How can we control the ultrafast transport of the spin and orbital angular momentum of electrons through nanostructures?
• How do lattice vibrations affect the angular momentum of electrons?
• How are dynamics modified close to interfaces?

A better understanding of the dynamics of quantum materials at their natural (terahertz) frequencies is highly relevant for future applications. The reason is that bit rates in information technology are gradually approaching the terahertz range, for instance, in wireless networks and field effect transistors. We also explore our results directly for applications in terahertz photonics, including the development of novel emitters, detectors and modulators of broadband terahertz radiation.

We participate in national and international research collaborations: the DFG-funded Cluster of Excellence 3112 on Chiral Electronics, the Collaborative Research Center/Transregio 227 on Ultrafast Spin Dynamics, SPP INTEREST-THz and FOR ChiPs as well as the EU-funded projects ORBITERA and ORBIS.
