Orbital excitations in LaMnO
Jeroen van den Brink
We study the recently observed orbital excitations, orbitons, and treat electron-electron correlations and lattice dynamics on equal footing. It is shown that the orbiton energy an…

Orbital effects in manganites
D. I. Khomskii
In this paper I give a short review of some properties of the colossal magnetoresistance manganites, connected with the orbital degrees of freedom. Ions Mn{3+}, present in most of…

Photoemission spectra of LaMnO3 controlled by orbital excitations
Jeroen van den Brink, Peter Horsch, Andrzej M. Oles
We investigate the spectral function of a hole moving in the orbital-ordered ferromagnetic planes of LaMnO, and show that it depends critically on the type of orbital ordering.…
