Dynamical Mean-Field Theory for Strongly Correlated Materials, of successes of dynamical mean-field theory, one of the most powerful theoretical methods in the field and the main topic of this book, in explaining different properties of strongly correlated materials when it is used both as a many-body theory and as an ab initio computational tool.

One-Band Hubbard Model: Definition and Early Solutionsng the power of dynamical mean-field theory (it will be introduced in the next chapter and is the main topic of the book) that allows one to accurately solve the Hubbard, and as result—to accurately describe physical properties of strongly correlated materials.

Multi-orbital and Cluster DMFT At the end of the chapter, we present some results obtained with these approaches, including phase diagrams for the 2D Hubbard model, and compare results obtained with the cluster and one-site DMFT approaches.

We conclude the chapter with a discussion of the relationship between DMFT and equivalent coherent potential approximation approaches used to study disordered systems.

Since usually the DMFT problem is solved in imaginary (Matsubara) frequency representation, in the second part of the chapter, we discuss two methods to perform analytical continuation of the obtained functions to the real-frequency domain, more convenient to analyze physical properties of the systems.
