I will show how ab initio approaches can be used to describe the ground and excited state properties of materials of different dimension and compositions. Density Functional Theory and Many Body approaches will be used to investigate the electronic structure and the optical features of semiconducting nanostructures as well of bulk metal-oxide. These atomic-scale approaches can be therefore useful to integrate the information obtained from model calculations and in particular to better interpret the experimental results. In particular I will show how “ab initio” theoretical spectroscopies can be used to study particular cases like transition metal oxides, which, with partially filled d- or f- shell, are considered a prototype of correlated materials, like perovskites or vanadium sesquioxides.
