Following the welcome address by Prof. Saskia F. Fischer and Prof. Thomas Schröder, an interesting program of presentations and talks further illustrated the scientific vision of JAMA. Dr. Olivio Chiatti and Linus Stahlberg, members of the ‘Novel Materials’ working group, gave an insight into JAMA's measurement technology and into transport phenomena and superconductivity in two-dimensional layers. Dr. Andreas Fiedler and Dr. Jens Martin from the IKZ introduced a modern perspective on new oxide semiconductor heterostructures and Si-based quantum materials. The ceremony was complemented by a lecture given by Prof. Thomas Filk from the University of Freiburg, who celebrated the milestones of quantum mechanics and looked back on the 100-year history of this fundamental theory. Prof. Ignacio Farías from the Institute of European Ethnology at the Humboldt-Universität zu Berlin then shed light on the significance of waves and their effect in contemporary urbanism, which is being investigated, among other things, as part of the Cluster of Excellence "Matters of Activity". A particular highlight of the ceremony was the musical performance ‘One or Two of Six Strange Strings’ by Prof. Alberto de Campo from the Berlin University of the Arts, which impressively highlighted the interaction between science and art.
Following the lectures, a poster session was held in the foyer, where participants had the opportunity to exchange ideas and engage in discussion. At the same time, fascinating experiments were presented in a JAMA-show, including a superconducting levitation train (figure) and an acoustic levitator, which illustrated the basics of some of the new laboratory's physical phenomena. Selected crystals with explanations were provided by the IKZ for demonstration purposes. Interested guests were also given the opportunity to experience the equipment and technology of the JAMA during a guided tour of the lab.
At JAMA, researchers analyze new electronic materials, in particular modern semiconductor and superconductor heterostructures. Nano- and quantum structures are also investigated using high-precision voltage, current and noise measurements. This includes the determination of material-specific parameters as well as the investigation of topological and quantum effects that are used in modern electronics or in future quantum technologies. Research focuses on surface and interface effects in charge, spin and heat transport that occur in complex material systems consisting of metals, semiconductors, superconductors and topological insulators. JAMA thus makes it possible to investigate new electronic materials for unknown physical phenomena. In an interdisciplinary and institutional co-operation, basic research is carried out with a view to future applications, thus strengthening the training of young researchers.
