New materials from uncharted places

Over the past decades, quantum materials – materials in which quantum phenomena govern physical properties – have become essential for everyday applications. In most cases, technological advances are driven by the discovery of new solid-state materials and a deeper understanding of the existing ones.

In this talk, I will show different families of solid-state materials discovered in our group. We develop empirical tools for targeting new materials with desired properties.1,2 We can access materials that so far remained out of reach3–5 due to their toxicity, radioactivity, or air sensitivity. Furthermore, we develop new ways to study materials on the micro-scale.6–8 From a chemical perspective, we are looking at systems ranging from crystallographically simple9 to very complex.1 In superconductors, we tune the critical temperature by making minute changes in the crystal structure.10,11 Among magnetic compounds, we examine not only strongly correlated systems that host exceptionally heavy electron masses at low temperatures,1 but also room temperature magnets that have application potential.12 Our experimental explorations go hand-in-hand with theory – we have targeted and confirmed a plethora of topological features.9 Moreover, we go beyond the bulk, scaling down to 2D and 1D – in order to explore the emergent phenomena and functionalities.
