Study of untreated problems enabled by the partial macroscopic averaging of microscopic nonlocal optical response theory

对于由微观非局部磁化率的长波近似导出的宏观电磁响应的第一性原理理论，我们进行了(A)适合于微观和宏观组分混合使用的几种模型案例的数值研究，以及(B)将该理论与其他可能形式的单一磁化率方案进行了比较。这显示了该理论的自然和最先进的性质，提供了电流密度作为宏观物质变量的磁化率的量子力学表达。

With respect to the first-principles theory of macroscopic EM response derived from the long wavelength approximation of microscopic nonlocal susceptibility, we performed (A) the numerical study of several model cases appropriate for the mixed use of micro- and macroscopic components, and (B) a comparison of this theory with other possible forms of single susceptibility schemes, which shows the natural and most advanced nature of this theory providing the quantum mechanical expression of susceptibility for current density as macroscopic matter variable.
