Abstract: Superconductivity—one of the most profound quantum phenomena discovered prior to the establishment of quantum mechanics—continues to drive today’s exciting developments in quantum materials, condensed matter physics, and quantum technologies. In this talk, I will discuss exciting new frontiers of superconductivity enabled by the advent of two-dimensional (2D) quantum materials. I will first highlight a series of discoveries regarding gate-induced superconductivity in a 2D topological excitonic insulator, which exhibits a unique phase diagram featuring an unconventional quantum critical point that cannot be explained by established theories. I will then discuss new opportunities enabled by a novel 2D nanochemistry approach we recently invented for nano-engineering superconductivity in moiré topological materials. The possibilities of investigating superconductivity in moiré-based fractionalized electronic systems will be envisioned.
