WebFeb 5, 2024 · Abstract. In the ordinary mean field theory, the effective field is static. If one allows temporal variation of the effective field, fluctuation effects of the corresponding field can be included. The correlation problem in a large system is then replaced by a single-site problem surrounded by a dynamical effective medium.

http://hauleweb.rutgers.edu/downloads/ Dynamical mean-field theory (DMFT) is a method to determine the electronic structure of strongly correlated materials. In such materials, the approximation of independent electrons, which is used in density functional theory and usual band structure calculations, breaks down. Dynamical mean-field theory, a non-perturbative treatment of local interactions between electrons, bridges the gap between the nearly free electron gas limit and the atomic limit of condensed-matter physics.
