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.

We have established ultrafast scanning tunnelling spectroscopy on the femtosecond time, atomic length and milli-electron-volt energy scale. This has allowed us to directly resolve the energy shift of a single atomic defect in a monolayer of tungsten diselenide due to drum-like phonon vibrations.
The results obtained in a close collaboration with the groups of Jascha Repp (University of Regensburg) and Jan Wilhelm (University of Regensburg) have appeared in Nature Photonics....

In close collaboration with the groups of Dominique Bougeard (UR) and Christoph Lange (TU Dortmund), we were able to reach record-breaking, deep-strong light-matter coupling with a coupling strength of up to 3.19. This, for the first time, creates vacuum ground state populations exceeding 1 virtual excitation quantum.
The results have been published in Nature Communications....

The new Graduate Research Training Group 2905 - "Ultrafast nanoscopy - from single particle dynamics to cooperative processes" - will be funded for five years.
The program will start April 2024 and allows graduate researchers to unveil the internal dynamics of the elementary building blocks of matter. Novel concepts of nanovideography will be pioneered to resolve atomic-scale dynamics and to trace ensuing cooperative processes in systems of increasing complexity directly in ultraslow-motion pictures. The discoveries could find applications in future nano- and optoelectronics, quantum technologies and green technologies.

Directly watching in slow-motion videos how electrons move in quantum mechanical orbitals and how this motion shapes the functionalities of condensed matter has been a dream shared by all natural and life sciences. Yet, this vision comes with the daunting challenge of mapping the microscopic structure of electronic orbitals with simultaneous ultrafast time resolution.
We will turn orbital cinematography into reality.

| Would you like to delve into the nanocosm and use state-of-the-art ultrafast nanoscopy techniques to investigate the inner workings of matter? What if you could even do that simultaneously at Angström spatial and femtosecond temporal scales?
Our group has vacant positions for young scientists at the Master's and PhD level to join us in cutting edge research and measurement techniques, opening the doors to solving fundamental and previously untouchable fields in nanoscale light-matter interaction, high-temperature super-conductivity, exciton dynamics and more.
