A computational method to obtain optical conductivities from first principles is presented. It exploits a relation between the conductivity and the complex dielectric function, which is constructed from the full electronic band structure within the random‐phase approximation. In contrast to the Drude model, no empirical parameters are used. As interband transitions as well as local‐field effects are properly included, the calculated spectra are valid over a wide frequency range. As an…
