Welcome to the Huber group at the University of Regensburg!
Many of the fundamental laws and unexpected phenomena in condensed matter physics are caused by extremely fast dynamics of electrons and ions on the femtosecond time (1 fs = 10-15 s) and terahertz frequency scale (1 THz = 1012 Hz). Unravelling such ultrafast processes is the main interest of our research. We develop next-generation, high-intensity femtosecond laser sources and THz technology, and employ them to explore novel femtophysics.

We have developed an approach based on ultrafast near-field microscopy that has allowed us to probe the nanoscale topography, crystallographic phase and chemical composition of metal halide perovskite films, while simultaneously extracting the ultrafast vertical carrier dynamics from femtosecond shifts in the pump-induced response following photoexcitation. This has revealed a surprising robustness of vertical charge transport towards nanoscale structural and compositional variations.
The results obtained in a close collaboration with the group of Michael Johnston (University of Oxford) have appeared in Nature Photonics.

We have discovered an entirely unforeseen quantum-mechanical contrast mechanism that finally enables all-optical microscopy to achieve atomic resolution while retaining subcycle temporal precision. This new concept allows us to directly trace the quantum flow of electrons on their intrinsic length and time scales.
The results obtained in a close collaboration with the group of Jan Wilhelm (University of Regensburg) have appeared in Nature.
