Development of a high accuracy electronic structure theory : Quantum Monte Carlo method using electronic configurations

量子蒙特卡罗（QMC）方法是利用随机数求解薛定谔方程的方法。在这项研究中，我们开发了一种新的QMC方法，其中电子被视为电子配置，而不是粒子。这种方法的一个优点是可以避免QMC方法中的一个重要问题--试探波函数依赖。我们编写了这种新方法的并行程序。在试验计算中得到了精确解。

The quantum Monte Carlo (QMC) method is the method to solve the Schrodinger equation by using random numbers. In this study, we developed a new QMC method in which electrons are treated as electronic configurations instead of particles. A merit of this method is that we can avoid the trial wave function dependence that is an important problem of the QMC method. We wrote a parallel program of this new method. The exact solutions were obtained in test calculations.
