Fractional charges and spin-charge separation in one-dimensional Wigner lattices
M. Daghofer, P. Horsch
We study density response N(k,omega) and one-particle spectra A(k,omega) for a Wigner lattice model at quarter filling using exact diagonalization. We investigate these observables…
Magnetic properties of spin-orbital polarons in lightly doped cobaltates
M. Daghofer, P. Horsch, G. Khaliullin
We present a numerical treatment of a spin-orbital polaron model for Na_xCoO_2 at small hole concentration (0.7 < x < 1). We demonstrate how the polarons account for the peculiar m…
Temperature effects in a spin-orbital model for manganites
M. Daghofer, D. R. Neuber, A. M. Oles +1
We study a two-dimensional effective orbital superexchange model derived for strongly correlated e_g electrons coupled to t_{2g} core spins in layered manganites. One finds that th…
Doping dependence of spin and orbital correlations in layered manganites
M. Daghofer, A. M. Oles, D. R. Neuber +1
We investigate the interplay between spin and orbital correlations in monolayer and bilayer manganites using an effective spin-orbital t-J model which treats explicitly the e_g orb…
