Who We Are

We study ultrafast phenomena in quantum materials.

A strong focus lies on the angular momentum of electrons (spin+orbit) and of the crystal lattice.

The associated processes often coincide with the femtosecond time scale and, thus, terahertz frequency scale.

Consequently, to study such extremely fast dynamics, we develop novel tools like ultrafast ampere-meters, ohm-meters and strong terahertz voltage sources, which greatly rely on femtosecond optical pulses and ultrabroadband terahertz electromagnetic transients.

To better understand our experimental results, we work out simple theoretical models.

Important questions we address include the writing and reading of magnetic information, the ultrafast transport of the spin and orbital angular momentum of electrons, and the impact of lattice vibrations on the angular momentum of electrons.

Our fundamental scientific insights are relevant for applications in information technology where bit rates are approaching the THz range.

We also explore our results directly for applications in THz photonics, including the development of novel emitters, detectors and modulators of broadband THz radiation.
