Our lab investigates quantum phenomena which focus on the interplay between correlations and topology. This intriguing interplay allows to develop unique realizations of non-abelian quasi-particles (qps) which are neither Boson nor Fermion-like. Among the phases which host these qps are the well-known fractional quantum Hall effect, topological superconductivity, and the recently emerging field of moire-superlattcies (twistronics). We are developing experiments in these arrowheads to unravel this intriguing physics. This line of research often utilizes quantum materials whose reduced dimensionality enhances quantum effects. We profit from the use of various van der Waals (vdW) materials (graphene, hBN, TMDs, etc.) as well as high-mobility two-dimensional GaAs electron gas, which are both grown in our department. Fabrication is performed in a state-of-the-art clean room facility, specially designed for vdW materials nanofabrication. These devices will be measured with transport techniques including quantum Hall interferometry, Josephson interferometry, capacitance measurements, thermal transport, and shot noise measurements. These measurements require high magnetic fields and low electron temperatures. Our lab will be equipped with an 8mK wet dilution refrigerator with a 20T magnet, a 7mK dry dilution with a 3D vector magnet, as well as a variable temperature cryostat. Funding is available for three years. Advantage for prior experience with: vdW materials, fabrication techniques, transport measurements and cryogenic systems. Interested candidates should send CV and list of publications to yuval.ronen@weizmann.ac.il
