论文摘要
Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid to a strongly correlated two-dimensional electron system with properties that are extraordinarily sensitive to carrier density and to controllable environmental factors such as the proximity of nearby gates and twist-angle variation.在其他现象中，魔术角扭曲的双层石墨烯具有超导性，相互作用诱导的绝缘状态，磁性，电子nematicition，线性在-T-T中的低温电阻率和量化异常霍尔状态。我们重点介绍了该领域的一些关键研究结果，指出了保持开放的重要问题，并评论了魔术角扭曲的双层石墨烯在密切相关的量子物质世界中。
Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid to a strongly correlated two-dimensional electron system with properties that are extraordinarily sensitive to carrier density and to controllable environmental factors such as the proximity of nearby gates and twist-angle variation. Among other phenomena magic-angle twisted bilayer graphene hosts superconductivity, interaction induced insulating states, magnetism, electronic nematicity, linear-in-T low-temperature resistivity, and quantized anomalous Hall states. We highlight some key research results in this field, point to important questions that remain open, and comment on the place of magic angle twisted bilayer graphene in the strongly correlated quantum matter world.
