在简要介绍了货车范德华力的基础上，我们回顾了Eberlein和Zietal最近提出的一种计算中性但可极化原子与任意形状的理想导电表面之间色散货车范德华力的方法。这种方法的优点是量子问题与静电学中相应的经典问题以一种启发性的方式联系起来，因此只需要计算一个合适的绿色函数。我们展示了如何静电的图像方法可以方便地使用一起的Eberlein和Zietal方法（当图像的解决方案是已知的）。然后，我们说明这种方法在一些简单但重要的情况下，包括大气系统。最后，我们给出了原子与接地导电材料制成的老板帽之间的货车范德华力的原始结果。(C)2013年美国物理教师协会。[http：//dx.doi.org/10.1119/1.4798548]
After a brief survey of van der Waals forces, we review a method recently proposed by Eberlein and Zietal to compute the dispersion van der Waals interaction between a neutral but polarizable atom and a perfectly conducting surface of arbitrary shape. This method has the advantage of relating the quantum problem to a corresponding classical one in electrostatics in an enlightening way so that all one needs is to compute an appropriate Green function. We show how the image method of electrostatics can be conveniently used together with the Eberlein and Zietal method (when the image solution is known). We then illustrate this method in some simple but important cases, including the atom-sphere system. Finally, we present an original result for the van der Waals force between an atom and a boss hat made of a grounded conducting material. (C) 2013 American Association of Physics Teachers.
