Abstract

We present a method to calculate optical properties of strongly correlated systems. It is based on dynamical mean-field theory and it uses as an input realistic electronic structure obtained by local density-functional calculations. Numerically, tractable equations for optical conductivity, which show a correct noninteracting limit, are derived. Illustration of the method is given by computing optical properties of the doped Mott insulator La 1-xSrxTiO3.
