Chiral magnons in altermagnetic RuO2
Libor Šmejkal, Alberto Marmodoro, Kyo-Hoon Ahn +8
Magnons in ferromagnets have one chirality, and typically are in the GHz range and have a quadratic dispersion near the zero wavevector. In contrast, magnons in antiferromagnets ar…
Kondo quasiparticle dynamics observed by resonant inelastic x-ray scattering
M. C. Rahn, K. Kummer, A. Hariki +18
Effective models focused on pertinent low-energy degrees of freedom have substantially contributed to our qualitative understanding of quantum materials. An iconic example, the Kon…
Sensitivity of the MnTe valence band to orientation of magnetic moments
Paulo E. Faria Junior, Koen A. de Mare, Klaus Zollner +3
An effective model of the hexagonal (NiAs-structure) manganese telluride valence band in the vicinity of the A-point of the Brillouin zone is derived. It is shown that while for th…
Valence skipping, internal doping and site-selective Mott transition in PbCoO under pressure
Atsushi Hariki, Kyo-Hoon Ahn, Jan Kuneš
We present a computational study of PbCoO at ambient and elevated pressure. We employ the static and dynamic treatment of local correlation in form of density functional theory…
Pressure-induced excitations in the out-of-plane optical response of the nodal-line semimetal ZrSiS
J. Ebad-Allah, S. Rojewski, M. Vöst +9
The anisotropic optical response of the layered, nodal-line semimetal ZrSiS at ambient and high pressure is investigated by frequency-dependent reflectivity measurements for the po…
Ferromagnetism of LaCoO films
Andrii Sotnikov, Kyo-Hoon Ahn, Jan Kuneš
We study ferromagnetic ordering and microscopic inhomogeneity in tensile strained LaCoO using numerical simulations. We argue that both phenomena originate from effective super…
