In a collaboration with the group of Ermin Malic (University of Marburg), we demonstrated proximity-controlled strong-coupling between phonons and electrically neutral excitons at atomically sharp interfaces of WSe2/gypsum heterostructures, creating new exciton-phonon mixed eigenmodes, called excitonic Lyman polarons. These findings could enable new man-made phase transitions in artificially stacked materials.

Together with our long-term collaborators Mack Kira (University of Michigan, Ann Arbor) and Stephan W. Koch (Philipps Universität Marburg), we have developed an all-optical way of mapping out electronic band structures of even tiny flakes of quantum materials in ambient air. Our approach uses a new concept called momentum combs to achieve super-resolution, which could help us to tailor emerging quantum materials and pave the way for advanced energy technologies and quantum computers.

In close collaboration with the groups of Jascha Repp (UR) and Angel Rubio (Max Planck Institute for the Structure and Dynamics of Matter, Hamburg), we found a way to map out atom-scale lightwave dynamics. Using a single-molecule switch, which senses changes in the local electromagnetic fields, we were able to quantitatively detect atom-scale near-field waveforms in the junction of a scanning tunneling microscope.

Together with our collaborators from Jascha Repp's group and Nikolaj Moll, we have found a fascinating way to push a select atom with controlled forces so quickly that we can choreograph the motion of a single molecule within less than a trillionth of a second.

Together with the groups of Prof. Dr. Miriam S. Vitiello (Pisa) and Prof. Dr. Edmund Linfield (Leeds) we developed a new group of saturable absorbers in the terahertz spectral domain based on ultra-strong coupling of intersubband transitions to the resonant mode of a microresonator. These new devices could enable passive mode locking of future quantum cascade lasers.

In close collaboration with the group of Dominique Bougeard and with Cristiano Ciuti (Université de Paris), we managed to switch off deep-strong light-matter coupling much faster than a cycle of light. Our breakthrough provides a very unusual glimpse behind the virtual photon dress of electrons, which helps unravelling the nature of vacuum fluctuations. In the future, even chemical reactions or superconductivity may be triggered merely by abrupt modification of the quantum vacuum.

In a collaboration with the groups of Ermin Malic, John Lupton, and Janina Maultzsch, we resolved the internal atom-like structure of excitons in a stack of two atomically thin monolayers of WSe2. Merely by changing the stacking angle, we find a drastic renormalization of the binding energy and lifetime as well as a highly tunable exciton-exciton interaction. These results pave the way for tailoring novel phases of matter in a broad range of van der Waals heterostructures.

Congratulations to Christoph Lange who has just started a new chair entitled "THz spectroscopy" at the Technische Universität Dortmund, beginning April 1, 2020. In his new group, Christoph will pursue new directions of THz cavity quantum electrodynamics on the subcycle scale. We wish him all the best for a successful start and look forward to continuing our successful collaboration!... more

We can now quantify the electric field distribution in the vicinity of an oscillating tip of a near-field microscope, which is a crucial prerequisite for performing quantitative nano-tomography and for expanding the limits of the lateral resolution.
The results are reported in ACS Photonics....
