Manganites at quarter filling: Role of Jahn-Teller interactions (2004)
Bała, J., Horsch, P., Mack, F.
We have analyzed different correlation functions in a realistic spin-orbital model for half-doped manganites. Using a finite-temperature diagonalization technique the CE phase was found in the...
CE correlations in a spin-orbital model for half-doped manganites (2004)
Using a finite-temperature diagonalization technique for a root8 x root8 site cluster, the charge-exchange phase was found to be stabilized together with charge order by the cooperative Jahn-Teller...
Orbital polarons in LaMnO3 (2002)
Bała, J., Oleś, A. M., Horsch, P.
We investigate the spectral functions and orbital correlation functions relative to the position of an e,. hole moving in the ferromagnetic plane of orbitally ordered LaMnO3. Polarization of orbitals...
Orbital-lattice polarons in ferromagnetic LaMnO3 (2002)
Bała, J., Oleś, A. M., Sawatzky, G. A.
We investigate the combined influence of superexchange and electron-phonon interactions on the excitation spectra and on hole propagation in a ferromagnetic plane of LaMnO3. The Jahn- Teller effect...
Quasiparticles and the structure of orbital polarons in ferromagnetic LaMnO3 (2002)
Bała, J., Oleś, A. M., Horsch, P.
We investigate the spectral functions and orbital-correlation functions relative to the position of an e(g) hole moving in the ferromagnetic plane of orbitally ordered LaMnO3. Solving this problem in...
