Strongly correlated topological flat bands in the novel class of moiré materials

Twist-angle engineering of 2D materials has led to the recent discoveries of novel many-body ground states in moiré systems such as correlated insulators, unconventional superconductivity, strange metals, orbital magnetism and topologically nontrivial phases. These systems are clean and tuneable, where all phases can coexist in a single device, which opens up enormous possibilities to address key questions about the nature of correlation induced superconductivity and topology, and allows to create entirely novel quantum phases with enhanced interactions. In this talk we will introduce some of the main concepts underlying these systems, concentrating on magic angle twisted bilayer graphene (MATBG) and show how we can engineer strongly interacting, topological and superconducting states. We will further discuss our recent effort to explore the vast library of novel bilayer moiré materials (TMDs etc.) using a novel high-throughput quantum twisted microscope (QTM) technique, which will allow us to search for novel exotic ground states with ever higher interactions energy and temperatures. Last but not least we will show some recent quantum technology developments that were enabled by the ultra-low carrier density superconducting states in MATBG, culminating in the demonstration of highly tuneable single photon detectors.
