Electronic Structure calculations for correlated materials - where do we stand? 

Electronic structure calculations for correlated electron materials have witnessed tremendous progress in recent years due to the development of combined density functional and many body theories. We will give an introduction to the field, with applications to transition metal compounds and f-electron systems [1].

 Making such calculations truly predictive requires to treat the Coulomb interactions (and screening thereof) entirely from first principles, that is, without using adjustable parameters. We will describe some recent developments along these lines, focussing in particular on the description of dynamical screening effects [2].

Finally, we will point out further perspectives and future directions in the field.
