Electronic structure calculations of strongly correlated electron systems by the dynamical mean-field method

We review some aspects of the realistic implementation of the dynamical mean-field theory. We extend some dynamical mean-field techniques to include the calculations of transport coefficients. The approach is illustrated on ${\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Sr}}_{x}{\mathrm{TiO}}_{3}$ material undergoing a density-driven Mott transition.
