非结构网格上求解量子电子动力学的无矩阵求逆方法

Matrix Inverse Free Method for Solving Quantum Electron Dynamics on Unstructured Grid

Katsuhiro Watanabe, Akihito Kikuchi

摘要:

提出了一种求解含时薛定谔方程的无矩阵求逆方法。该方法不受哈密顿量形式的限制,采用结构化、非结构化等真实空间网格系统,即使采用非结构化网格系统对复杂区域进行调整,也能实现N阶算法。我们已经证明了一些具有非薛定谔型哈密顿量的误差估计问题的精确解和应用,并且我们成功地模拟了所有情况下波函数的时间演化。

英文摘要:

A matrix inverse free method to solve time-dependent Schrodinger equation is presented. The method is not subject to form of Hamiltonian and adopting real space grid system such as structured and unstructured grid, and achieves the order N algorithm even if we adopt unstructured grid systems to adjust complex regions. We have demonstrated some error evaluation problems that have exact solution and application in which it has non-Schrodinger type Hamiltonian, and we have successfully simulated the time-evolution of wave function for all of the case.
