Dr S.R. Wiedmann (Steffen)
Associate professor - FELIX Laboratory
Member - Gender and Diversity committee
Associate professor - High Field Magnet Laboratory
S. Wiedmann is an expert in the area of the electronic and thermodynamic properties of condensed matter with a focus on quantum materials in which topology and/or electronic correlations play a dominant role. He is actively involved in the development of novel experimental techniques and approaches to investigate and understand the underlying physical phenomena and functionalities derived from the confluence of many-body interactions and topological protection.Research theme

Research grants and prizes
- 2020 - Driving quantum phase transitions in topological correlated matter (TOPCORE) - ENW Groot More information
- 2012 - VENI fellowship - No electrons inside Electrical resistance has been understood for more than a century. Topological insulators, a recently discovered new class of materials, have the unique characteristic of only conducting electricity on the surface. This project will focus on their fundamental characteristics in high magnetic fields.
