Joshua Mornhinweg receives the dissertation prize of the faculty of physics!

We congratulate Joshua Mornhinweg on being awarded the Dissertation Prize by the Faculty of Physics at the University of Regensburg for his remarkable PhD thesis, titled "Tailoring and Non-Adiabatic Control of Deep-Strong Light-Matter Coupling." This prize, sponsored by the Wilhelm and Else Heraeus Foundation, recognizes an exceptional doctoral thesis in physics and comes with an endowment of €4000.

Vertical voyage in metal halide perovskites

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. ... more

Atomic-scale telegraphy with light

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.

Quantum dance to the beat of a drum: Coverstory in Nature Photonics

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.
