摘要翻译:
我们发展了一种精确计算任意致密物体之间的Casimir能的方法,无论是电介质还是理想导体。能量是由量子电流涨落产生的多极之间的相互作用获得的。物体的形状和组成只能通过它们的散射矩阵进入。当包含所有多极子时,结果是准确的,并且收敛迅速。低频展开产生的能量是以物体大小与分离之比的级数表示的。作为一个例子,我们得到了两个介质球的这个级数和完全导电球在所有分离处的全相互作用。

英文摘要:
We develop an exact method for computing the Casimir energy between arbitrary compact objects, either dielectrics or perfect conductors. The energy is obtained as an interaction between multipoles, generated by quantum current fluctuations. The objects' shape and composition enter only through their scattering matrices. The result is exact when all multipoles are included, and converges rapidly. A low frequency expansion yields the energy as a series in the ratio of the objects' size to their separation. As an example, we obtain this series for two dielectric spheres and the full interaction at all separations for perfectly conducting spheres.
