横向耦合层中的磁输运
Magnetic transport in laterally coupled layers
摘要：
我们讨论了磁输运的两个相邻的硬壁层暴露在一个均匀的场垂直于层平面和横向耦合通过一个条形窗口的共同边界的系统。我们表明，光谱是一个绝对连续的和平带的组合，后者是目前只有当两层的宽度是相称的，并推导出它们的属性。我们还分析了单侧几何中的屏障分离的两个层是一个半平面。
英文摘要：
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.
