The Quantum Opto-Electronics research group, led by Prof. Tomasz Smoleński at the Department of Physics, University of Basel, Switzerland, is seeking a highly motivated PhD student to join a cutting-edge project funded by an ERC Starting Grant. The group specializes in low-temperature magneto-optical and quantum-optical spectroscopy, focusing on strongly correlated electronic, excitonic, and spin phenomena in tunable, low-dimensional quantum materials, particularly van der Waals (vdW) heterostructures. This PhD position is part of the OptoQuantTOP ERC Starting Grant project, which aims to achieve optical control over strongly correlated topological phases of matter. The successful candidate will play a key role in exploring collective many-body phenomena through magneto-opto-electronic experiments conducted under extreme conditions, including temperatures as low as ~10 mK and magnetic fields up to ~10 T. The research will involve manipulating correlated topological phases of matter using light at ultrafast time scales, with the goal of developing a new generation of optically-programmable topological circuits. Students will have access to state-of-the-art facilities, including dry low-temperature magneto-optical cryostats, dilution refrigerators with optical access, pulsed laser systems, and clean-room device fabrication equipment. The position offers a unique opportunity to help establish a new magneto-optical laboratory and to work with advanced apparatus for ultra-low temperature spectroscopy and sample fabrication. The University of Basel provides a stimulating academic environment, with internationally recognized research groups in both experimental and theoretical condensed matter physics. The research team is dynamic and newly established, fostering a collaborative spirit and high interaction among members, which is ideal for professional growth and research development. The university offers internationally competitive salaries and social benefits, in accordance with its guidelines, and the city of Basel provides a vibrant, international setting at the crossroads of Switzerland, France, and Germany. Eligibility requirements include a Master's degree (or near completion) in Physics, Nanoscience, Electrical/Optical Engineering, or related fields, with a strong background in condensed matter physics and optics. Candidates should be familiar with data analysis and programming (Python, C++, Labview), and possess excellent communication, teamwork, and presentation skills. A demonstrated research track record in condensed matter physics is highly valued, and experience in magneto-optical spectroscopy, device fabrication, clean-room processing, and computer-based simulations (COMSOL) is desirable. Proficiency in English is required. Applications should include a CV, a statement of scientific interests (max. 1 page), a publication list, transcripts with grades, and contact details for at least two references. Apply via the online recruiting platform. For more information, visit the group website or contact Prof. Tomasz Smoleński directly. Applications are reviewed on a rolling basis until the position is filled, with a formal deadline of February 13, 2026.
