This PhD position in solid state physics focuses on the study of entanglement and topology in Kondo systems, a cutting-edge area within correlated quantum materials. The project is a joint effort between the Institute of Solid State Physics at Technische Universität Wien (TU Wien) in Vienna and the Institut Laue-Langevin (ILL) in Grenoble, offering a unique international research environment. The research aims to explore multipartite entanglement and emergent topology in quantum materials, building on recent discoveries such as high multipartite entanglement in strange metals and the Weyl-Kondo semimetal phase. The successful candidate will employ high-resolution inelastic neutron scattering under extreme conditions (very low temperatures, high magnetic fields, and potentially high pressures) as the primary experimental technique. Experiments will be conducted mainly at the ThALES three-axis spectrometer at ILL, with additional time-of-flight measurements. The project also involves developing and applying advanced data analysis methods, including background subtraction, determination of absolute units, and possibly polarization analysis. The PhD student will be based at ILL in Grenoble but enrolled at TU Wien, splitting time between both institutions. This arrangement allows for extended research stays at ILL, participation in the ILL Graduate School, and integration into the Quantum Materials research unit at TU Wien. The candidate will have access to state-of-the-art infrastructure for supporting research, including crystal growth, characterization, and complementary property measurements. The position is funded by ILL for an initial period of three years, with a likely extension managed by TU Wien. The gross monthly salary is 2,722.84 EUR. The start date is as soon as possible, and applications will be considered until the position is filled. Applicants should have a strong background in solid state physics, excellent experimental skills, and ideally experience with (neutron) scattering experiments. The position is ideal for highly motivated candidates eager to work at the intersection of quantum materials, experimental physics, and advanced data analysis in a collaborative international setting. To apply, send your CV, publication and presentation list, a short statement of research experience and interests, and two letters of recommendation (sent separately by referees) to Prof. Dr. Silke Bühler-Paschen at [email protected]. For further information, contact Silke Bühler-Paschen, Arno Hiess, or Paul Steffens.

This position offers an exciting opportunity for a Postdoctoral Researcher or PhD Student to join the Quantum Materials group at Technische Universität Wien (TU Wien) in Vienna, Austria. The research focuses on microwave spectroscopy of quantum materials, specifically strange metals and correlated topological semimetals. Quantum materials are at the forefront of next-generation quantum device development, and this project aims to investigate the electrodynamic response of strongly correlated electron systems using advanced microwave-based measurement techniques. The successful candidate will employ and optimize various microwave techniques, including broadband optical conductivity measurements in Corbino geometry and superconducting coplanar waveguide resonators. These methods are implemented in a powerful closed-cycle dilution refrigerator, enabling studies at millikelvin temperatures. The research will involve thin film samples grown by molecular beam epitaxy, targeting phenomena such as strange metallicity and correlation-driven topology in heavy fermion compounds. The Quantum Materials group at TU Wien is located at the Karlsplatz campus in central Vienna and is renowned for its comprehensive research, ranging from materials synthesis to advanced physical property measurements under extreme conditions. The group is actively involved in major research projects, including an ERC Advanced Grant, and collaborates internationally with theorists and experimentalists. The working environment is highly interdisciplinary and offers access to large research facilities. Applicants should possess a strong background in solid state physics and demonstrate excellent experimental skills. While experience with cryogenic equipment, dilution refrigerators, or microwave/RF measurements is desirable, it is not mandatory. Programming skills in Python for instrument control, data acquisition, and analysis are considered advantageous. The position is open to both PhD students and postdoctoral researchers, with competitive salaries: approximately 2,830 EUR/month for PhD students and 5,014 EUR/month for postdocs, paid 14 times per year, in accordance with the Austrian Collective Agreement for University Staff. To apply, candidates should send their CV, a list of publications and presentations, a short statement of research experience and interests, and two letters of recommendation (emailed separately by the writers) to Prof. Dr. Silke Bühler-Paschen at [email protected]. Applications will be considered until the position is filled. For further information, applicants are encouraged to contact Prof. Dr. Silke Bühler-Paschen directly. This opportunity is ideal for motivated researchers interested in quantum materials, microwave spectroscopy, and experimental solid state physics, offering a vibrant academic environment and access to cutting-edge facilities in Vienna.
