Physicists at Technische Universität Kaiserslautern in the team of Professor Dr. Herwig Ott have succeeded for the first time in directly observing collisions between highly excited atoms, so-called Rydberg atoms, and atoms in the ground state. Particularly interesting is that they can precisely identify the energy states of the individual atoms, which was impossible until now. The researchers have developed a custom microscope for this purpose, with which they were able to directly measure the momenta of the atoms. The processes observed are important for understanding interstellar plasma and ultracold plasmas generated in the laboratory. The study was published in the renowned journal “Nature Communications”.

Presenting our recent work “Concurrent magneto optical imaging and magneto-transport readout of electrical switching of insulating antiferromagnetic thin films” [Appl. Phys. Lett. 117, 082401 (2020) https://doi.org/10.1063/5.0011852 in a talk and a live Q&A session, Felix Schreiber received the Best Student Presentation Award for his talk at the MMM 2020 virtual conference. The online event featured over 1000 sessions reviewing the latest advances in both fundamental and applied magnetism. The work is a result of a collaboration with the group of J. Sinova within the TopDyn - Dynamics and Topology Research Centre.
