Moiré-driven band renormalization and quantum transport in twisted 2D materials

Abstract Moiré superlattices formed in twisted two-dimensional (2D) materials provide a highly tunable platform to investigate strongly correlated quantum phenomena. Recent advances have revealed a rich landscape of interaction-driven phases, including correlated insulators, superconductivity, magnetism, and fractional topological states, many of which are inaccessible in conventional materials. This review provides an overview of moiré-induced quantum phases, focusing on their underlying mechanisms and recent progress toward zero-magnetic-field fractional states. We aim to provide an integrated perspective bridging fundamental physics and potential applications in quantum electronics.
