Short-range magnetic order and multi-stage phase transitions in the easy-plane van der Waals magnet CrCl
T. B. Mazitov, M. I. Panin, A. S. Pakhomov +4
We investigate the evolution of spin correlations and the nature of the multi-stage magnetic transition in the quasi-two-dimensional easy-plane van der Waals magnet . B…
The pseudogap in high- superconductors from SU(2) gauge symmetry and dynamic correlation effects
I. A. Goremykin, A. A. Katanin
We consider the spectral properties of the two-dimensional Hubbard model, describing the electronic properties of high- compounds, within the SU(2) gauge theory, which assumes…
Magnetism and symmetry of superconducting gap in LaFeAsO from dynamical mean-field theory
S. L. Skornyakov, V. I. Anisimov, A. A. Katanin
By employing a combined method of density functional theory and dynamical mean field theory (DFT+DMFT) we investigate the effect of electronic correlations on the magnetic and supe…
Suppression of local magnetic moment formation and paramagnetic exchange interactions in monolayer FeGeTe
A. A. Katanin, A. N. Rudenko, D. I. Badrtdinov +1
We study the electronic and magnetic properties of monolayer FeGeTe within the DFT+DMFT approach in the paramagnetic phase. We argue that this compound is sufficiently far…
Magnetic properties of monolayer, multilayer, and bulk CrTe
A. A. Katanin, E. M. Agapov
We investigate magnetic properties of CrTe within the density functional theory (DFT) approach in ferromagnetic phase and combination of DFT and dynamical mean field theory (DF…
Giant exciton binding energy in bulk CrCl3
Georgy Ermolaev, Tagir Mazitov, Anton Minnekhanov +20
Van der Waals (vdW) materials, with their unique combination of electronic, optical, and magnetic properties, are emerging as promising platforms for exploring excitonic phenomena.…
