Abstract

We consider the van der Waals interaction between two ground-state atoms, placed inside a cylindrical waveguide. It is shown that the interaction can be enhanced or suppressed by several orders of magnitudes. Even though the effect is most spectacular for an ideal perfectly reflecting wall, it survives when realistic properties of the wall materials are taken into account. Different types of the waveguide wall, including perfectly reflecting wall, walls made of gold and silicon, and Bragg-distributed wall are compared. It is shown in particular that the van der Waals interaction is inhibited by material absorption.

强烈增强和抑制圆柱波导内原子间范德华相互作用

摘要

我们考虑放置在圆柱形波导内的两个基态原子之间的范德华相互作用。结果表明，相互作用可以增强或抑制几个数量级。即使对于理想的完美反射墙而言，效果最为壮观，但考虑到墙材的真实属性后，效果仍然存在。比较了不同类型的波导壁，包括完全反射的壁，金和硅制成的壁以及布拉格分布的壁。特别显示出范德华相互作用被材料吸收所抑制。
