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…
Spin-lattice couplings in ferromagnets: analysis from first-principles
I. P. Miranda, M. Pankratova, M. WeiÃenhofer +8
Magnetoelasticity plays a crucial role in numerous magnetic phenomena, including magnetocalorics, magnon excitation via acoustic waves, and ultrafast demagnetization/Einstein-de Ha…
Plasmonic waveguides in two-dimensional materials: a quantum mechanical description using semiclassical techniques
T. M. Koskamp, M. I. Katsnelson, K. J. A. Reijnders
Plasmons are likely to play an important role in integrated photonic ciruits, because they strongly interact with light and can be confined to subwavelength scales. These plasmons…
Superconductivity of Bad Fermions: Origin of Two Gaps in HTSC Cuprates
E. A. Stepanov, S. Iskakov, M. I. Katsnelson +1
We investigate the spectral properties of the doped Hubbard model with parameters typical for high-temperature cuprate superconductors. Our approach is based on a novel st…
