X-ray scattering studies of strongly correlated materials: orbital ordering in KCuF3 and stripe-like domain structures in BiFeO3 epitaxial thin films
… orbital ordering model based on the archetypical Kugel-Khomskii model. Our modified Kugel-Khomskii model takes into account direct orbital exchange interactions due to a combination of electron-electron interactions and charge transfer effects. The effect of this term is to create a near …

Orbital order in iron-based superconductors
… strong-coupling theories, with emphasis on the Kugel-Khomskii model. Chapter 4 deals with the orbital order in the weak-coupling theories and its experimental consequences. Finally in Chapter 5, we propose the degenerate double-exchange model, and show how the orbital order in the itinerant …
