Local magnetic moment formation and Kondo screening in the half filled two dimensional single band Hubbard model

T. B. Mazitov, A. A. Katanin

We study formation of local magnetic moments in strongly correlated Hubbard model within dynamical mean field theory and associate peculiarities of temperature dependence of local…

Generalized dynamical mean-field theory of two-subalttice systems with non-local interactions and its application to study charge and spin correlations in graphene

A. A. Katanin

We investigate magnetic and charge correlations in graphene by using the formulation of extended dynamical mean-field theory (E-DMFT) for two-sublattice systems. First, we map the…

Magnetic, charge, and transport properties of graphene nanoflakes

V. S. Protsenko, A. A. Katanin

We investigate magnetic, charge and transport properties of hexagonal graphene nanoflakes (GNFs) connected to two metallic leads by using the functional renormalization group (fRG)…

Extracting Kondo temperature of strongly-correlated systems from the inverse local magnetic susceptibility

A. A. Katanin

The temperature scales of screening of local magnetic and orbital moments are important characteristics of strongly correlated substances. In a recent paper X. Deng et al. using dy…

Itinerant magnetism of chromium under pressure: a DFT+DMFT study

A. S. Belozerov, A. A. Katanin, V. I. Anisimov

We consider electronic and magnetic properties of chromium, a well-known itinerant antiferromagnet, by a combination of density functional theory (DFT) and dynamical mean-field the…

The non-analytic momentum dependence of spin susceptibility of Heisenberg magnets in paramagnetic phase and its effect on critical exponents

A. A. Katanin

We study momentum dependence of static magnetic susceptibility in paramagnetic phase of Heisenberg magnets and its relation to critical behavior within nonlinear sigma model…
