摘要: 将费曼路径积分理论引入量子力学教学,用来分析光子干涉现象.对非简并的两光子和三光子干涉的关联函数进行了推导,并对干涉结果进行了模拟. 模拟结果显示,非简并的多光子干涉是多光子聚束和量子拍效应叠加的结果.

关键词: 多光子干涉, 路径积分理论, 量子拍

Abstract: The Feynman’s path integral theory is introduced into quantum mechanics

teaching,and used to analyze photon interference. The correlation functions of nondegenerate

two - photon and three-photon interference are derived. The results of interference are

simulated. The simulate results show that multi-photon interference of nondegenerate

  photons results from the superposition of multi-photon bunching and quantum beating effect.

Key words: multi-photon interference, path-integral theory, quantum beating
