The Quantum Matter Lab at the Niels Bohr Institute, University of Copenhagen, invites applicants for postdoctoral fellowships to investigate topologically protected synthetic matter in 1D and 2D arrays of semiconductor-superconductor Josephson junctions formed in a variety of lattices. The project aims to explore novel states and dynamics of emergent quantum states, including topological matter and flat bands. The expected start date is July 1, 2026, or later by agreement.
