Abstract
We review some aspects of the realistic implementation of the dynamical mean-field method. We extend the techniques introduced in Ref.[A. Georges, G. Kotliar, W. Krauth, and M.J. Rozenberg, Rev. Mod. Phys. 68, 13 (1996)] to include the calculations of transport coefficients. The approach is illustrated on La1-xSrxTiO3 material undergoing a density driven Mott transition.
