高分子干涉测量中相干损失的分析

Analysis of the loss of coherence in interferometry with macromolecules

A. Viale, M. Vicari, N. Zanghi'

摘要:

我们提供了一个独立的量子描述的干涉产生的大分子衍射光栅,特别是参考富勒烯干涉实验。我们分析的过程中引起损失的相干性包括在光束准备(准直设置和热扩散的波长的大分子)和环境干扰。结果表明,与Zeilinger的小组发表的实验数据吻合良好,并突出了与光学的类比。我们的分析为规划未来的实验提供了一些提示。

英文摘要:

We provide a self-contained quantum description of the interference produced by macromolecules diffracted by a grating, with particular reference to fullerene interferometry experiments. We analyze the processes inducing loss of coherence consisting in beam preparation (collimation setup and thermal spread of the wavelengths of the macromolecules) and in environmental disturbances. The results show a good agreement with experimental data published by Zeilinger's group and highlight the analogy with optics. Our analysis gives some hints for planning future experiments.
