本文提出了一种简单的迭代格式,大大方便了离散路径积分的计算。将该方法应用于研究质子在势能面中的运动,并将所得的组态分布函数与路径积分Monte Carlo计算和“精确"结果进行了比较。作为第二个例子,我们提出了计算的径向分布函数的Ar 2货车的德瓦尔斯二聚体在两个温度下。
A simple iterative scheme which greatly facilitates the evaluation of discretized path integrals is presented. The method is applied to study the motion of a proton in a bistable potential and the resulting configurational distribution function is compared to both the path integral Monte Carlo calculation and to the ‘‘exact’’ result. As a second illustration we present calculations of the radial distribution function for an Ar2 van der Waals dimer at two temperatures.
