Spin, orbital and quasi-particle excitations in doped vanadates

Abstract

A theory of doped vanadium oxides with long-range spin and t2g orbital orders is presented. The spin, orbital and quasi-particle excitations are calculated by the Schwinger-boson approach associated with the self-consistent Born approximation. It is shown that the quasi-particle spectra associated with the t2g orbital excitations are remarkably different from those of the spin excitations as well as those of the eg orbital excitations.
