标题： Dislocation Patterning as a Mechanism for Flat Band Formation

摘要： 我们计算了自由电子气与从现代位错量子理论导出的有效电子-位错势相互作用的电子色散关系的二阶修正。 我们的结果表明，特定应变场和方向下的位错图案会在电子色散中诱导各向异性的平带，称为“魔法”参数。 当应变或方向偏离这些魔法参数时，这些平带会获得非零的曲率。 显示英文摘要

摘要： We compute the second-order correction to the electronic dispersion relation of a free electron gas interacting with an effective electron-dislocation potential, derived from a modern quantized theory of dislocations. Our results demonstrate that dislocation patterning induces anisotropic flat bands in the electronic dispersion under specific strain fields and directions, referred to as ``magic'' parameters. These flat bands acquire non-zero curvature as the strain or direction deviates from these magic parameters.
