Twisted graphene is a material formed by the misaligned stacking of two graphene layers, with very rich electronic structures and properties. Our research will focus on studying the electronic transport characteristics of twisted graphene, especially its behavior at low temperatures and strong magnetic fields. Additionally, we will advance the in-depth understanding of novel physical properties in this system, such as electronic strong correlations, topology, and magnetism. Specifically, we will study its superconducting effects, quantum Hall effects, quantum anomalous Hall effects, and other phenomena. By deeply understanding these properties, we aim to provide new breakthroughs for the future development of nanoelectronics and quantum information fields.
