论文摘要
我们提出了一种分裂和诱导算法，以递归地找到一般紧密结合结构的散射矩阵。散射矩阵允许使用Landauer公式直接计算介观系统中的传输特性。该方法是准确的，通过分析方形，三角形和蜂窝晶格的算法的性能，与其他最先进的递归和非恢复方法相比，我们显示出显着改善。
We propose a divide-and-conquer algorithm to find recursively the Scattering matrix of general tight-binding structures. The Scattering matrix allows a direct calculation of transport properties in mesoscopic systems by using the Landauer formula. The method is exact, and by analyzing the performance of the algorithm in square, triangular and honeycomb lattices, we show a significant improvement in comparison to other state-of-the-art recursive and non-recursive methods.
