Rudi Hackl, a member of the Leibniz Institute for Solid State and Materials Research Dresden (IFW Dresden) since many years, has been awarded a Fellowship of the American Physical Society (APS), Division of Condensed Matter Physics, for “his pioneering experiments on inelastic light scattering on novel quantum materials, probing the nature of unconventional superconductivity, charge density waves, and density fluctuations near critical points”. This fellowship is awarded to APS members for excellence in physics and exceptional service to the physics community.
In addition, he has also been selected as an APS “Outstanding Referee” for being exceptionally helpful in assessing manuscripts for publication in the APS journals.
Hackl’s research area is in the field of novel superconducting materials. In the materials he investigates, strong interactions between electrons trigger new phases including superconductivity. Hackl's most important achievements were the observation of unconventional superconductivity in cuprates having a gap with line nodes and of sharp lines inside the nearly clean gap of iron-based superconductors. Both observations are essential indications of the underlying mechanism for Cooper pairing and the main reason for his award as an APS Fellow.
Under his leadership, in October the IFW Dresden hosted the international workshop "Novel Superconductors 2024: Materials, Properties, Applications and Perspectives". This state of research conference was supported by DFG and IFW Dresden. 71 scientists from ten countries and three continents presented their latest results on unconventional superconducting materials and the related theoretical approaches towards understanding their properties.
The materials discussed included PtBi2, a material that has come into special focus at the IFW Dresden in recent months (Press Release 09/02/2024).
Congratulations to Rudi Hackl on both accounts!

About Prof. Dr. Rudolf Hackl
Rudi Hackl received his PhD from the Technical University Munich in 1987. In 1988 he became a postdoctoral researcher at the Walther Meissner Institute of the Bavarian Academy of Sciences and Humanities and was tenured 1990. He received the Habilitation from the Budapest University of Science and Economics in 1998. He became Lecturer in 2010 and was appointed e.o. Professor in 2020. In 2024 he was elected Fellow of the American Physical Society. His main focus was light scattering studies of correlated electron systems, specifically superconductors. He and his group observed the unconventional d-wave nature of the energy gap in the copper-oxygen compounds and sub-leading pairing channels in the iron-based superconductors which demonstrate the importance of magnetism for the Cooper pairing.
