Magnetic polarons due to spin-length fluctuations in spin-orbit Mott systems
Jan Revenda, Krzysztof Wohlfeld, Jiří Chaloupka
Mott insulators based on and transition-metal ions, where spin-orbit interaction plays a key role, can exhibit various forms of unusual magnetism. A particular example is…
Circular Dichroism in Resonant Inelastic X-ray Scattering: Probing Altermagnetic Domains in MnTe
D. Takegami, T. Aoyama, T. Okauchi +11
X-ray magnetic circular dichroism provides a means to identify ferromagnetic, chiral, and altermagnetic orders via their time-reversal-symmetry () breaking. However, d…
Phase diagram and spin correlations of the Kitaev-Heisenberg model: Importance of quantum effects
Dorota Gotfryd, Juraj Rusnačko, Krzysztof Wohlfeld +3
We explore the phase diagram of the Kitaev-Heisenberg model with nearest neighbor interactions on the honeycomb lattice using the exact diagonalization of finite systems combined w…
Role of the upper branch of the hour-glass magnetic spectrum in the formation of the main kink in the electronic dispersion of high-T cuprate superconductors
Dominique Geffroy, Jiří Chaloupka, Thomas Dahm +1
We investigate the electronic dispersion of the high-T cuprate superconductors using the fully self-consistent version of the phenomenological model, where charge pl…
Evidence for a superconducting origin of prominent features of the in-plane infrared response of underdoped cuprates and implications of their persistence above
Břetislav Šopík, Jiří Chaloupka, Dominik Munzar
We report on results of our analysis of published experimental data of the in-plane infrared response of two representative underdoped high- cuprate superconductors…
Microscopic gauge-invariant theory of the c-axis infrared response of bilayer cuprate superconductors and the origin of the superconductivity induced absorption bands
J. Chaloupka, C. Bernhard, D. Munzar
We report on results of our theoretical study of the c-axis infrared conductivity of bilayer high-Tc cuprate superconductors using a microscopic model involving the bilayer-split (…
