Aula Rasetti (Dip. di Fisica - Edificio G. Marconi)

In this talk I will first review the basic concepts of the merging of Density Functional Theory with Many-Body Perturbation Theory in the case of equilibrium phenomena. I will discuss merits and drawbacks also discussing the key aspects of the competition between electronic--mediated and phononic--mediated scattering processes. I will particularly concentrate on the less known electron-phonon interaction treated in a fully Ab-Initio manner. Then I will present a novel approach based on the merging of Non-Equilibrium Green's function theory and Density Functional Theory to investigate the carrier dy! namics following a pump excitation in a pump probe experiment.
