标题： Using atomic interference to probe atom-surface interaction

摘要： 我们表明，从两个适当极化的倏逝波反射的原子干涉对原子-表面相互作用中的色散效应敏感，这取决于特定的实验参数。 我们研究了原子德布罗意波长较短和较长的情况。 前一种情况在半经典近似（兰道-泽纳模型）下进行分析。 后一种情况代表了一个量子 regime，并通过数值求解相关的耦合薛定谔方程进行分析。 我们考虑了一个具体的实验方案，并展示了铷（短波长）和更轻的亚稳态氦原子（长波长）的结果。 然后讨论了每种情况的优点。 显示英文摘要

摘要： We show that atomic interference in the reflection from two suitably polarized evanescent waves is sensitive to retardation effects in the atom-surface interaction for specific experimental parameters. We study the limit of short and long atomic de Broglie wavelength. The former case is analyzed in the semiclassical approximation (Landau-Zener model). The latter represents a quantum regime and is analyzed by solving numerically the associated coupled Schroedinger equations. We consider a specific experimental scheme and show the results for rubidium (short wavelength) and the much lighter meta-stable helium atom (long wavelength). The merits of each case are then discussed.
