We discuss the main features of this multi-orbital quantum impurity solver for the Anderson impurity model, dynamical mean field theory as well as its coupling to density functional theory.The … Webas determined with density functional theory, which also provides a suitable basis). Then the interaction must be treated reliably, and for this dynamical mean-field theory (DMFT) and re-lated theories provide a controlled approach. The spirit and some technical aspects of DMFT were already mentionedin the Lecture of D. Vollhardt.
