Stefan Löffler

Assoc. Prof. Dr.techn. Dipl.-Ing. Stefan Löffler is an academic at TU Wien, affiliated with the USTEM (Electron Microscopy) group and Atominstitut. His career includes roles as Assistant Professor (2018–2023), Habilitation (2023), and current position as Associate Professor since 2023 (likely a typo for 2023). He holds a Dipl.-Ing. (MSc) from TU Wien and Uppsala University (2009) and a PhD (Dr. techn.) from TU Wien (2013). Postdoc positions included TU Wien and the Canadian Centre for Electron Microscopy at McMaster University (2015–2016).

Research focuses on electron vortex beams, energy-loss magnetic chiral dichroism (EMCD), orbital mapping, and quantum phenomena in electron microscopy. His work bridges materials science, catalysis, and quantum mechanics, addressing topics like CO₂ conversion, nanomaterials, and superconductivity. Over 60 peer-reviewed papers and contributions to high-impact journals like Nature Communications and Physical Review Letters reflect his interdisciplinary impact.

Key techniques developed include orbital mapping via 4D energy-filtered STEM and quantum logic gates using electron vortices. His group collaborates globally, with projects on catalytic materials for CO₂ utilization and advanced electron microscopy instrumentation for sub-nanometer resolution. Current research trends emphasize quantum imaging, energy storage materials, and theoretical foundations of electron optics.

He teaches and advises in materials characterization and quantum phenomena, with labs at TU Wien’s Freihaus and Atominstitut locations. Future work includes exploring topological quantum states and improving EMCD applications for magnetic material analysis.
