摘要: 用路径积分的分析方法求得了一维无限深势阱中粒子的传播函数,并由传播函数导出了粒子的波函数和能量,展示了路径积分与传统方法的等价性,同时还介绍了一种有用的数学函数——雅可比θ3函数.

Abstract: A method to calculate the propagator for a particle moring in a one-dimensional infinite square well using Feynman' s path integral is presented. Wave function and energy spectrum are derived from the propagator, which manifest the equivalence between path integral and traditional methods. Meanwhile, a interesting mathematical function, Jacobi theta function θ3, is introduced.

Key words: infinite square potential well, path integral, Jacobi theta function
