Conventional Coulomb engineering, through controlled manipulation of the environment, offers an effective route to tune the correlation properties of atomically thin van der Waals…
Dynamic heterogeneity in the self-induced spin glass state of elemental neodymium
L. Niggli, J. H. Strik, Z. Liu +4
Spin glasses are magnetic materials exhibiting numerous magnetization patterns, that randomly vary both in real space and in time. To date, it is still not well understood what the…
Optical detection of 4-spin chiral interaction in a 2D honeycomb ferrimagnet
Bektur Murzaliev, Mikhail Katsnelson, Mikhail Titov
Broken inversion symmetry of magnetic lattice is normally described by Lifshitz invariants in micromagnetic energy functional. Three exceptions are the lattices with T…
Electronic correlations arising from anti-Stoner spin excitations: an ab initio study of itinerant ferro- and antiferromagnet
S. Paischer, D. Eilmsteiner, M. I. Katsnelson +2
The anti-Stoner excitations are a spin-flips in which, effectively, an electron is promoted from a minority to a majority spin state, i.e., complementary to Stoner excitations and…
Good plasmons in a bad metal
Francesco L. Ruta, Yinming Shao, Swagata Acharya +12
Correlated materials may exhibit unusually high resistivity increasing linearly in temperature, breaking through the Mott-Ioffe-Regel bound, above which coherent quasiparticles are…
Phonon-induced renormalization of exchange interactions in metallic two-dimensional magnets

Robert Sokolewicz, Mikhail Baglai, Ivan Ado +2
A finite spin life-time of conduction electrons may dominate Gilbert damping of two-dimensional metallic anti-ferromagnets or anti-ferromagnet/metal heterostructures. We investigat…

Understanding spin-lattice interactions in antiferromagnets is one of the most fundamental issues at the core of the recently emerging and booming fields of antiferromagnetic spint…
Observation of Kekulé vortices induced in graphene by hydrogen adatoms
Y. Guan, C. Dutreix, H. Gonzales-Herrero +5
Fractional charges are one of the wonders of the fractional quantum Hall effect, a liquid of strongly correlated electrons in a large magnetic field. Fractional excitations are als…
