原子-表面相互作用物理

The Physics of Atom-Surface Interactions

Carsten Henkel

摘要:

一个教程概述是由电磁场介导的原子和表面之间的相互作用。重点是分散(或范德华)力和过渡引起的热波动在近场的表面。冷原子在表面附近的微观陷阱(“原子芯片”)中的应用为这堂理论课提供了实验背景。我们不包括化学物理方面,是在原子尺度的距离,如表面上的吸附和扩散,纳米结构的生长,或从结晶表面原子束衍射相关。这些都是由其他讲师。

英文摘要:

A tutorial overview is given on interactions between atoms and surfaces that are mediated by the electromagnetic field. The emphasis is on dispersion (or van der Waals) forces and transitions induced by thermal fluctuations in the near field of a surface. Applications with cold atoms held in microscopic traps near surfaces ("atom chips") provide the experimental background for this theory lecture. We do not cover the chemical physics aspects that are relevant at distances comparable to the atomic scale, like adsorption and diffusion on surfaces, growth of nanostructures, or atomic beam diffraction from crystalline surfaces. These are covered by other lecturers.
