摘要
从某种意义上说，由许多原子构成的簇可被视为一个大原子。了解此类簇的介电特性后, 可用于评估簇之间或簇与表面之间的范德华 (dispersion) 相互作用形式。本文推导了这两种极端相反分离 regime 下的相互作用:完全滞后和非滞后。在完全滞后 regime (very large separation) 中,相互作用的大小仅由簇 (s) 的静态极化率决定。在非滞后 regime (small separation) 中,我们采用簇极化率的单一共振频率模型来推导相互作用系数的表达式。 presented for numerical examples to demonstrate that many-body screening of these interactions can be significant. The results represent the corrections to the commonly used approximation of pairwise additivity of interatomic interactions. 虽然许多体筛选这些相互作用可能具有重要意义。结果代表了对常用近似（即原子相互作用的两两可加性）的修正。
