The dynamical susceptibility of strongly correlated electronic systems can be calculated
within the framework of dynamical mean-field theory (DMFT). The required measurement of …

Dynamical mean-field theory describes the impact of strong local correlation effects in many-
electron systems. While the single-particle spectral function is directly obtained within the …

It is shown that a minimum realization of the dynamical mean-field theory (DMFT) can be
achieved by mapping a correlated lattice model onto an impurity model in which the impurity …

The dynamical mean field theory (DMFT) has emerged as one of the most important
frameworks for theoretical investigations of strongly correlated lattice models and real …

In this paper, we revisit the antiferromagnetic (AF) phase diagram of the single-band three-
dimensional half-filled Hubbard model on a simple cubic lattice studied within the dynamical …

By means of the dynamical vertex approximation (D Γ A) we include spatial correlations on
all length scales beyond the dynamical mean-field theory (DMFT) for the half-filled Hubbard …

Computing momentum-dependent susceptibilities in the dynamical mean-field theory
(DMFT) requires solving the Bethe-Salpeter equation, which demands large computational …

Since the first investigation of the Hubbard model in the limit of infinite dimensions by
Metzner and Vollhardt, dynamical mean-field theory (DMFT) has become a very powerful …

We here present how a self-consistent solution of the dynamical mean-field theory equations
can be obtained using exact diagonalization of an Anderson impurity model with accuracies …

Extensions of dynamical mean-field theory (DMFT) make use of quantum impurity models as
nonperturbative and exactly solvable reference systems which are essential to treat the …
