WebThe Dynamical Mean Field Theory [Georges1996] (DMFT), goes beyond, by solving exactly the local correlations for an atom in an effective field (i.e., an Anderson model). The effective field reproduces the effect of the surrounding correlated atoms and is thus self-consistently related to the solution of the Anderson model [Georges1996] .

WebThe dynamical mean-field theory (DMFT) is a widely applicable approximation scheme for the investigation of correlated quantum many-particle systems on a lattice, e.g., electrons in solids and cold atoms in optical lattices. In particular, the combination of the DMFT with conventional methods for the calculation of electronic band structures ... 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.
