Orbital polarons in the metal-insulator transition of manganites
R. Kilian, G. Khaliullin
The metal-insulator transition in manganites is strongly influenced by the concentration of holes present in the system. Based upon an orbitally degenerate Mott-Hubbard model we an…

Orbital Dynamics: The Origin of Anomalous Magnon Softening in Ferromagnetic Manganites
G. Khaliullin, R. Kilian
We study the renormalization of magnons by charge and coupled orbital-lattice fluctuations in colossal magnetoresistance compounds. The model considered is an orbitally degenerate…
