The art of modeling in solid state physics & the current state of DMFT

The explanation of physical phenomena requires idealization and modeling. Models must be sufficiently simple, but not too simple. This strategy is illustrated in the case of ferromagnetism, where electronic correlations play an important role. They refer to effects which cannot be explained if the interaction acting on a particle is approximated by a static mean field. Here the Hubbard model is introduced as the minimal microscopic model describing correlated electrons. I will also introduce the generic mean-field theory for correlated electrons, the Dynamical Mean-Field Theory (DMFT), and discuss its foundations and current state.
