Strongly Correlated Electrons from the Perspective of Dynamical Mean-Field Theory (IMPRS-UFAST Focus Course)
Strong electronic correlations are a main driver behind many exciting phenomena in quantum many-body systems, ranging from correlated quantum materials (Mott transition, high-temperature superconductivity) to cold atoms in optical lattices. However, the strong-correlation problem still poses many challenges when it comes to a quantitative and even qualitative understanding of the relevant degrees of freedom and microscopic interactions that drive phase transitions in solids. Dynamical mean-field theory (DMFT), first developed in the late 1980s and 1990s, provides one key limit in which the correlation problem becomes tractable, namely the one of large spatial dimensions, or local self-energies. In this focus course we will discuss the basics behind DMFT and learn how this allows one to understand the paradigmatic Mott metal-to-insulator transition.
