Evolution of Spin-Orbital Entanglement with Increasing Ising Spin-Orbit Coupling
Dorota Gotfryd, Ekaterina Paerschke, Krzysztof Wohlfeld +1
Several realistic spin-orbital models for transition metal oxides go beyond the classical expectations and could be understood only by employing the quantum entanglement. Experimen…
Origin of monoclinic distortion and its impact on the electronic properties in KO
Olga Sikora, Dorota Gotfryd, Andrzej Ptok +4
We use the density functional theory and lattice dynamics calculations to investigate the properties of potassium superoxide KO in which spin, orbital, and lattice degrees of f…
How spin-orbital entanglement depends on the spin-orbit coupling in a Mott insulator
Dorota Gotfryd, Ekaterina M. Paerschke, Jiri Chaloupka +2
The concept of the entanglement between spin and orbital degrees of freedom plays a crucial role in understanding various phases and exotic ground states in a broad class of materi…
Kitaev-like honeycomb magnets: Global phase behavior and emergent effective models
Juraj Rusnačko, Dorota Gotfryd, Jiří Chaloupka
Compounds of transition metal ions with strong spin-orbit coupling recently attracted attention due to the possibility to host frustrated bond-dependent anisotropic magnetic intera…
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…
Quantum phase transitions in the Kitaev--Heisenberg model on a single hexagon
Dorota Gotfryd, Andrzej M. Oleś
We present a detailed analysis of the Kitaev--Heisenberg model on a single hexagon. The energy spectra and spin--spin correlations obtained using exact diagonalisation indicate qua…
