Spin-orbital physics in the optical conductivity of quarter-filled manganites
Jan Bala, Peter Horsch
Using finite-temperature diagonalization we investigate the optical conductivity and spin-orbital dynamics in the CE phase of half-doped manganites. We find character…

Manganites at Quarter Filling: Role of Jahn-Teller Interactions
Jan Bała, Peter Horsch, Frank Mack
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…
