Electronic correlations stemming from nearly flat bands in van der Waals materials have demonstrated to be a powerful playground to engineer artificial quantum matter, including superconductors, correlated insulators and topological matter. This phenomenology has been experimentally observed in a variety of twisted van der Waals materials, such as graphene and dichalcogenide multilayers. Here we show that spontaneously buckled graphene can yield a correlated state, emerging from an elastic pseudo Landau level. Our results build on top of recent experimental findings reporting that, when placed on top of hBN or NbSe 2 substrates, wrinkled graphene sheets relax forming a periodic, long-range buckling pattern. The low-energy physics can be accurately described by electrons in the presence of a pseudo-axial gauge field, leading to the formation of sublattice-polarized Landau levels. Moreover, we verify that the high density of states at the zeroth Landau level leads to the...

自发屈曲石墨烯的弹性朗道能级的相关性

范德华材料中几乎平坦的带产生的电子相关性已被证明是工程化人工量子物质（包括超导体，相关绝缘体和拓扑物质）的强大场所。在各种扭曲的范德华材料中，例如石墨烯和二卤化双金属多层膜中，已经通过实验观察到了这种现象。在这里，我们显示自发屈曲的石墨烯可以产生相关态，从弹性伪兰道能级出现。我们的结果建立在最新的实验发现之上，该发现表明，当将石墨烯片放置在hBN或NbSe 2衬底上时，其起皱作用会松弛，形成周期性的，长期的屈曲图案。在存在伪轴距场的情况下，电子可以准确地描述低能物理学。导致形成亚晶格极化的朗道能级。此外，我们验证了在零Landau级别上的高密度状态导致...
