三缝模型中多路径干涉现象的概率研究

RESEARCH ON THE PROBABILITY DISTRIBUTION OF THIRD-ORDER INTERFERENCE IN THREE-PATH MODEL

波动性是量子力学区别于经典力学的显著特点之一.干涉模型是研究这一特性的理想工具,本文运用路径积分的方法,在三缝干涉模型中研究了多路径干涉现象的概率分布.在不同尺寸的三缝干涉模型中,我们发现三阶干涉的分布概率占比发生了变化.结果表明,三阶干涉的概率分布受到系统环境的影响.

The wave nature of quantum system is one of the distinguishing features from classical mechanics.The multi-slit interference model is an ideal tool to explore it.Using the path integral,we derive the particle′s probability distribution in three-path model.We find the probability distribution of third-order interference varies with the certain experimental parameters.It shows that the third-order interference is affected by the environments.
