硬核/连续混合势的分子动力学算法

A molecular-dynamics algorithm for mixed hard-core/continuous potentials

Yao A. Houndonougbo, Brian B. Laird, Benedict J. Leimkuhler

摘要:

本文提出了一种新的分子动力学算法,用于积分连续/冲力混合作用下的质点系的运动方程。这种方法,我们称之为脉冲Verlet,是使用类似于那些已被成功地用于生成各种分子动力学积分算子分裂技术。在数值实验中,脉冲Verlet方法被证明是优于以前的方法在长期模拟的稳定性和能量守恒。

英文摘要:

We present a new molecular-dynamics algorithm for integrating the equations of motion for a system of particles interacting with mixed continuous/impulsive forces. This method, which we call Impulsive Verlet, is constructed using operator splitting techniques similar to those that have been used successfully to generate a variety molecular-dynamics integrators. In numerical experiments, the Impulsive Verlet method is shown to be superior to previous methods with respect to stability and energy conservation in long simulations.
