论文摘要
我们讨论了两个相邻的硬壁层系统中的磁运输，该层暴露于垂直于层平面的均匀磁场，并通过公共边界中的条形窗户侧面耦合。我们表明，频谱是绝对连续和平坦的带的组合，后者仅当两层的宽度相称并得出其性能时才存在。我们还分析了单方面的几何形状，其中将两层分开的屏障是半平台。
We discuss magnetic transport in the system of two adjacent hard-wall layers exposed to a homogeneous field perpendicular to the layer plane and coupled laterally through a strip-shaped window in the common boundary. We show that the spectrum is a combination of absolutely continuous and flat bands, the latter being present only if the widths of the two layers are commensurate, and derive their properties. We also analyze the one-sided geometry in which the barrier separating the two layers is a halfplane.
