I have removed, for the moment, the old main text. The first line does not really fit any more. Maybe one can reintroduce the citation in a more specific way?
Optical conductivity is a tool for studying the electronic states in materials.[1]
The following two sentences were taken verbatim from the beginning of section 4.1 of my thesis:
If a system is subjected to an external electric field then, in general, a redistribution of charges occurs and currents are induced. For small-enough fields, the induced polarization and the induced currents are proportional to the inducing field.
Similar formulation might be useful when adding a general derivation of the optical conductivity (along the lines of the mentioned chapter 4.1).

Basis in the etymology of physics edit
Either someone should provide a basis for this term that isn't simply derived from a recent usage. — Preceding unsigned comment added by Wikibearwithme (talk • contribs) 09:35, May 2, 2021 (UTC)
