Many of the optical and electronic properties of solids are caused by extremely fast dynamics of electrons on the femtosecond (1 fs = 10^-15 s) time scale. Our main interest is to trace ultrafast processes, while resolving the impact of interfaces, strong light-matter coupling, or local structural changes on the nanometer (1 nm = 10^-9 m) length scale. We are developing new methods to effectively capture nano-femto-dynamics, allowing us to record nanoscopic slow-motion pictures.

LATEST NEWS

Magnetic order traps quasi-1D excitons

? Brad Baxley, PtW

Experiments carried out in the group of Rupert Huber (UR), revealed how the antiferromagnetic spin alignment in adjacent layers of the van der Waals crystal CrSBr confines Coulomb-bound electron-hole pairs into one dimension. In a close collaboration with the groups of Mackillo Kira (University of Michigan), Zdeněk Sofer (University of Chemistry and Technology Prague) and Florian Dirnberger (Technical University of Munich), we also revealed the?internal structure and a strong fine-structure splitting of the excitons. These results were published in Nature Materials.

FUNDING

The group receives funding from the Bavarian State Ministry of Science and the Arts and the Elite Network of Bavaria for six years.

The central goal of the research project "Nano-femto-control of cooperative dynamics in van der Waals quantum materials" is to probe and control strong electronic correlations and pronounced collective excitations on their intrinsic femtosecond temporal and nanometer spatial scales. During the six-year funding period, the group will thus, for example, shed light onto tailored phase transitions in heterostructures of atomically thin van der Waals crystals.
