Numerical simulations are important for many systems. In particular, various standard computer programs have been developed for solving the quantum Schrödinger equations. However, the accuracy of these calculations is limited by computer capabilities. In this work, an iterative method is introduced to enhance the accuracy of these numerical calculations, which is otherwise prohibitive by conventional methods. The method is easily implementable and general for many systems.

数值模拟对于许多系统都很重要。特别是，已经开发出了各种标准的计算机程序来求解量子薛定谔方程。然而，这些计算的准确性受到计算机能力的限制。在这项工作中，引入了一种迭代方法来提高这些数值计算的准确性，否则传统方法是不可行的。该方法易于实现且适用于许多系统。
