Scientific paper

We study the dielectric response of correlated systems which undergo a Mott transition as a function of band filling within the dynamical mean field framework. We compute the dielectric figure of merit (DFOM), which is a measure of dielectric efficiency and an important number for potential device applications. It is suggested how the DFOM can be optimized in real transition metal oxides. The structures seen in the computed Faraday rotation are explained on the basis of the underlying local spectral density of the $d=\infty$ Hubbard model.
