球壳内物体的Casimir相互作用

Casimir interactions of an object inside a spherical metal shell

Saad Zaheer, Sahand Jamal Rahi, Thorsten Emig, Robert L. Jaffe

摘要:

我们研究电磁卡西米尔相互作用的对象包含在一个空的,完美的导电球壳。对于一个小的对象,我们提出了分析计算的力,这是指向远离腔的中心,和扭矩,这往往会对齐的对象相反的腔外的首选对齐。对于一个完美的导电球作为内部对象,我们计算的邻近力近似(PFA)的数值修正。在这两种情况下,内部配置的结果与相应的外部配置的结果平滑地匹配。

英文摘要:

We investigate the electromagnetic Casimir interactions of an object contained within an otherwise empty, perfectly conducting spherical shell. For a small object we present analytical calculations of the force, which is directed away from the center of the cavity, and the torque, which tends to align the object opposite to the preferred alignment outside the cavity. For a perfectly conducting sphere as the interior object, we compute the corrections to the proximity force approximation (PFA) numerically. In both cases the results for the interior configuration match smoothly onto those for the corresponding exterior configuration.
