Abstract The precise spatial engineering of quantum phases stands as a major challenge in condensed matter physics, with profound implications for fundamental science and quantum technologies. While moiré heterostructures have enabled remarkable tunability on the correlated states, the deterministic spatial manipulation of emergent quantum phases like superconductivity and magnetism remains an open challenge.

Abstract Moiré superlattices formed by stacking two-dimensional crystals offer a powerful platform for exploring strongly correlated and topological quantum phenomena. However, the absence of microscopic insights has long hindered a comprehensive understanding of their underlying nature and formation mechanisms.

Abstract The nature of the pseudogap state is widely believed as a key to understanding the pairing mechanism underlying unconventional superconductivity. Although pseudogap states have recently been realized in moiré systems with extensive gate tunability, their local electronic structure remains largely unexplored.
