Polarizability of a small sphere including nonlocal effects
Abstract
We develop a simple semiclassical method for calculating the polarizability of a very small spherical particle by taking into account the nonlocal nature of the dielectric response. Our theory is very general in the sense that it can be applied to any material which can be characterized by a bulk dielectric function of the form ${\ensuremath{\epsilon}}_{B}(\stackrel{\ensuremath{\rightarrow}}{\mathrm{k}},\ensuremath{\omega})$: We introduce a new additional boundary condition (ABC) which is similar but not exactly equivalent to the Fuchs-Kliewer ABC. The theory is applied to calculate the polarizabilities of dielectric and metallic spheres.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
