Chalcogenic orbital density waves in weak and strong coupling limit

Adam Kłosiński, Andrzej Michał Oleś, Cliò Efthimia Agrapidis +2

Stimulated by recent works highlighting the indispensable role of Coulomb interactions in the formation of helical chains and chiral electronic order in the elemental chalcogens, w…

Trimeron-phonon coupling in magnetite

P. Piekarz, D. Legut, E. Baldini +11

Using density functional theory, we study the lattice dynamical properties of magnetite (FeO) in the high-temperature cubic and low-temperature monoclinic phases. The calcu…

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…

Discovery of the soft electronic modes of the trimeron order in magnetite

Edoardo Baldini, Carina A. Belvin, Martin Rodriguez-Vega +9

The Verwey transition in magnetite (FeO) is the first metal-insulator transition ever observed and involves a concomitant structural rearrangement and charge-orbital orderi…

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…

Defect-induced orbital polarization and collapse of orbital order in doped vanadium perovskites

Adolfo Avella, Andrzej M. Oleś, Peter Horsch

We explore mechanisms of orbital order decay in doped Mott insulators (Sr,Ca)VO (Pr,Y,La) caused by charged (Sr,Ca) defects. Our unrestricted Hartree-Fock an…
