| Abstract: | A system of charged particles in a quantum ring consists of a great number of base vectors of eigenfunctions and Hamiltonian 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%. |
