摘要
对于量子环上带电粒子体系,组成本征函数的基矢数及哈密顿矩阵元素数都极大,数值计算量庞大.本文介绍在处理此问题时按轨道总角动量分类从基矢集中选择子基矢集的方法和技巧.应用计算机进行数值计算时,此方法比以往节省90%以上的时间.
A system of charged particles in a quantum ring consists of a great number of base vectors of eigenfunctions and Hamihonian matrix elements, resulting in a huge amount of numerical computations. This paper describes a method for solving the problem according to a classification of orbital angular momentum. It introduces technique to select sub-vector sets from eigenvectors. The method reduces the computation by more than 90%.
