A diagrammatic solution of the single-impurity Anderson model in the Kondo regime
A simplified parquet approximation is developed to the two-particle vertex of strongly correlated electrons so that electron-hole and -electron-electron irreducible vertices are determined self-consistently. We showed that the dominant contributions ...

Simplified parquet equations for the Anderson impurity model: comparison with numerically exact solutions
We use an analytic solver for the single-impurity Anderson model based on simplified parquet equations to describe the Kondo asymptotics. This scheme uses a two-particle self-consistency to control the strong-coupling Kondo...

Analytic impurity solver with Kondo strong-coupling asymptotics
An approximate analytic solution of the Anderson single impurity model is constructed. Using the parquet equations for the two-particle vertex, correct weak (Fermi liquid) and strong (Kondo) coupling regimes are qualitative...

Modeling of Co impurity in Cu host using DFT+ED
We investigate the electronic structure of a cobalt atom in a copper host using the density functional theory and the exact diagonalization of an Anderson impurity model. The spectral functions and spin moments at the i...

Kondo behavior in the asymmetric Anderson model: Analytic approach
Strong-coupling limit of the asymmetric single-impurity Anderson model is studied by means of a renormalized perturbation expansion with a two-particle self-consistency. A Kondo scale in two and one-particle spectral functi...

Magnetic properties of metallic impurities with strongly correlated electrons
We studied the effect of a magnetic field on the Kondo asymptotics in the single-impurity Anderson model. Inclusion of a spin polarized solution demands an extension of the existing approximate parquet scheme so that both s...

Single-impurity Anderson model out of equilibrium: A two-particle semianalytic approach
We apply a two-particle semianalytic approach to a single Anderson impurity attached to two biased metallic leads. The theory is based on reduced parquet equations justified in critical regions of singularities in the Bethe-Salpeter...
