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…
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…
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…
