This article is a short introduction to the modern computational techniques used to tackle the many-body problem in materials. The aim is to present the basic ideas, using simple examples to illustrate strengths and weaknesses of each method. We will

In a superconducting material, electrical resistivity abruptly disappears below a critical temperature. Discovered in solid mercury in 1911, superconductivity remained an unsolvable riddle until 1957, when physicists Bardeen, Cooper, and Schrieffer d

We investigate the magnetic couplings in ${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$ in the Mott-insulating picture, combining density-functional theory, dynamical mean-field theory, and many-body perturbation theory. We first determine the form of the ${j

We discuss a cost-effective approach to understand magnetic relaxation in thenew generation of rare-earth single-molecule magnets. It combines ab initio calculations of thecrystal field parameters, of the magneto-elastic coupling with local modes, an

The origin of orbital order in correlated transition-metal compounds is strongly debated. For the paradigmatic ${e}_{g}$ systems ${\mathrm{KCuF}}_{3}$ and ${\mathrm{LaMnO}}_{3}$, it has been shown that the electronic Kugel'-Khomskii mechanism alone i

We investigate the stability of $xy$ orbital ordering and the nature of the magnetic longitudinal excitations in ${\mathrm{Ca}}_{2}{\mathrm{RuO}}_{4}$. To this end, we employ the local-density approximation $+$ dynamical mean-field theory approach, i
