标题： Formal Integration of Electron Scattering Processes via Separation of Dynamical and Geometric Contributions

摘要： 通过将散射过程中的几何贡献与动力学贡献解耦，我们开发了一种计算连接到两个电极的一维相干导体中电子散射矩阵的方法。 特别是，我们证明在高能区域，传输矩阵趋于系统的贝里算子。 我们通过几个具有不同平面内磁场分布的示例展示了该方法。 值得注意的是，我们的结果揭示了实现近完美自旋翻转传输的可能性，突显了其在自旋电子学中的潜在应用。 显示英文摘要

摘要： By decoupling the geometric from the dynamical contributions in the scattering processes, we develop a method to compute the scattering matrix of electrons in a one-dimensional coherent conductor connected to two electrodes. In particular, we demonstrate that, in the high-energy regime, the transmission matrix converges to the Berry operator of the system. We showcase the method through several examples featuring different in-plane magnetic field profiles. Notably, our results reveal the possibility of achieving near-perfect spin-flip transmission, highlighting potential applications in spintronics.
