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…
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…
Spin-lattice couplings in ferromagnets: analysis from first-principles
I. P. Miranda, M. Pankratova, M. Weißenhofer +8
Magnetoelasticity plays a crucial role in numerous magnetic phenomena, including magnetocalorics, magnon excitation via acoustic waves, and ultrafast demagnetization/Einstein-de Ha…
Topological entanglement entropy to identify topological order in quantum skyrmions
Vipin Vijayan, L. Chotorlishvili, A. Ernst +3
We study the topological entanglement entropy and scalar chirality of a topologically ordered skyrmion formed in a two-dimensional triangular lattice. Scalar chirality remains a sm…
Topological dynamical quantum phase transition in a quantum skyrmion phase
Vipin Vijayan, L. Chotorlishvili, A. Ernst +3
Quantum skyrmionic phase is modelled in a 2D helical spin lattice. This topological skyrmionic phase retains its nature in a large parameter space before moving to a ferromagnetic…
Semiclassical theory for plasmons in two-dimensional inhomogeneous media
T. M. Koskamp, M. I. Katsnelson, K. J. A. Reijnders
The progress in two-dimensional materials has led to rapid experimental developments in quantum plasmonics, where light is manipulated using plasmons. Although numerical methods ca…
Exchange interactions in iron and nickel: DFT+DMFT study in paramagnetic phase
A. A. Katanin, A. S. Belozerov, A. I. Lichtenstein +1
We analyze possible ways to calculate magnetic exchange interactions within the density functional theory plus dynamical mean-field theory (DFT+DMFT) approach in the paramagnetic p…
Reconstruction of classical skyrmions from Anderson towers: quantum Darwinism in action
O. M. Sotnikov, E. A. Stepanov, M. I. Katsnelson +2
The development of the quantum skyrmion concept is aimed at expanding the scope of the fundamental research and practical applications for classical topologically-protected magneti…
Quantum simulator to emulate lower dimensional molecular structure
E. Sierda, X. Huang, D. I. Badrtdinov +7
Bottom-up quantum simulators have been developed to quantify the role of various interactions, dimensionality, and structure in creating electronic states of matter. Here, we demon…
Revised Tolmachev-Morel-Anderson pseudopotential for layered conventional superconductors with nonlocal Coulomb interaction
M. Simonato, M. I. Katsnelson, M. Rösner
We study the effects of static nonlocal Coulomb interactions in layered conventional superconductors and show that they generically suppress superconductivity and reduce the critic…
Sub-cycle multidimensional spectroscopy of strongly correlated materials
V. Valmispild, E. Gorelov, M. Eckstein +5
Strongly correlated solids are extremely complex and fascinating quantum systems, where new states continue to emerge, especially when interaction with light triggers interplay bet…
Semiclassical theory for plasmons in spatially inhomogeneous media
K. J. A. Reijnders, T. Tudorovskiy, M. I. Katsnelson
Recent progress in experimental techniques has made the quantum regime in plasmonics accessible. Since plasmons correspond to collective electron excitations, the electron-electron…
Spin dynamics of itinerant electrons: local magnetic moment formation and Berry phase
