Welcome to the future research group of Prof. Tomasz Smoleński at the University of Basel!

Our group will utilize low-temperature magneto-optical and quantum-optical spectroscopy to investigate collective electronic, excitonic, and spin phenomena in tunable atomically-thin quantum materials. In our lab, we will design and assemble new classes of highly-controllable van der Waals heterostructures and probe them with various opto-electronic techniques, including linear or non-linear spectroscopy, ultra-fast time-resolved experiments, super-resolution imaging etc. This will allow us to access novel strongly correlated phases of matter such as electronic crystals, topological liquids or unconventional magnets, as well as to explore their quantum phase diagrams with a variety of tuning knobs, such as bias voltage, magnetic field, strain, externally-tunable spatial confinement etc. This research will enable us not only to answer outstanding fundamental questions of condensed matter physics, but also to open new vistas for quantum technologies and quantum computing.

You can learn more about our research interests here.
