The emergence of strongly correlated electronic phases remains one of the unsolved puzzles of modern condensed matter physics. In low dimensions, the strength of interactions between electrons is enhanced, which make these systems prime candidate to understand the origin of emerging electronic phases, with the added benefit of metrology and quantum computing applications. Our research group combines nanofabrication of graphene structures, local probes and quantum transport at ultra-low temperatures to induce, control and explore strong electron interactions in one- and two-dimensional systems. We experimentally control the magnitude of electron-electron interactions in quantum materials to understand the interplay between quantum confinement, non-trivial topology and interaction strength.
