Large-scale moiré systems are extraordinarily sensitive, with even minute atomic shifts leading to significant changes in electronic structures. Here, we investigate the lattice relaxation effect on moiré band structures in twisted bilayer MoTe$_2$ with two approaches: (a) large-scale plane-wave basis first principle calculation down to $2.88^{\circ}$, (b) transfer learning structure relaxation + local-basis first principles calculation down to $1.1^{\circ}$. We use two types of van der Waals corrections: the D2 method of Grimme and the density-dependent energy correction, and find that the density-dependent energy correction yields a continuous evolution of bandwidth with twist angles. Based on the above results. we develop a more complete continuum model with a single set of parameters for a wide range of twist angles, and perform many-body simulations at $ν=-1,-2/3, -1/3$.

采用双层扭曲哈伯德模型研究了Sr 3 Ir 2 O 7的低能电子结构。Sr_3Ir_2O_7被认为是一种莫特绝缘体，并可用双层扭曲赝自旋1/2模型来描述。Sr_3Ir_2O_7中的双层扭曲带来了本征各向异性，系统不再是SU（2）不变的。各向异性选择一个容易的c轴共线反铁磁磁结构在低温下，打破了离散伊辛对称性。横向自旋激发是带隙的，纵向自旋激发是弱色散的。我们实现键算子平均场计算来描述的双层扭曲赝自旋1/2模型的磁性能与实验测量Sr 3 Ir 2 O 7。双层扭曲哈伯德模型被认为是Sr 3 Ir 2 O 7的低能电子结构的良好的零阶近似。
