Splitting of electronic spectrum in paramagnetic phase of itinerant ferromagnets and altermagnets

A. A. Katanin

We study self-energy effects induced by strong magnetic fluctuations in the paramagnetic phase of strongly-correlated itinerant magnets within the density functional theory combine…

Magnetic fluctuations and superconducting pairing in -iron

A. S. Belozerov, A. A. Katanin, V. Yu. Irkhin +1

We study Coulomb correlation effects and their role in superconductivity of -iron under pressure from 12 to 33 GPa by using a combination of density functional and dyn…

Non-Fermi-liquid behaviour and Fermi-surface expansion induced by van Hove-driven ferromagnetic fluctuations: the D-TRILEX analysis

Ilia S. Dedov, Andrey A. Katanin, Evgeny A. Stepanov

We consider the electronic and magnetic properties of the Hubbard model on a square lattice with the Fermi level near van Hove singularity and the ratio of the next-nearest-neighbo…

Frequency dependence of temporal spin stiffness and short-range magnetic order in the doped two-dimensional Hubbard model

I. A. Goremykin, A. A. Katanin

We study doping and temperature dependencies of temporal and spatial spin stiffnesses of the Hubbard model within the mean field approach for incommensurate magnetic order. We show…

Two distinct quantum critical behaviors in the doped two-dimensional periodic Anderson model

M. Kitatani, T. Schäfer, A. A. Katanin +2

We study quantum criticality in the doped two-dimensional periodic Anderson model with the hybridization acting as a tuning parameter. Employing the dynamical vertex approximation…

Magnetic properties of half metal from the paramagnetic phase: DFT+DMFT study of exchange interactions in CrO

A. A. Katanin

We study magnetic properties of CrO within the density functional theory plus dynamical mean-field theory (DFT+DMFT) approach in the paramagnetic phase. We consider the 3-orbit…
