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…

Optical conductivity of doped manganites: Comparison of ferromagnetic Kondo Lattice Models with and without orbital degeneracy
Frank Mack, Peter Horsch
The optical conductivity of the double exchange and the orbital degenerate Kondo lattice Hamiltonian (orbital t-J model) are invetigated by means of finite temperature diagonalizat…
