Ferromagnetic Polarons, Phase Separation, Stripes and Polaron Lattice: The two- and three-dimensional ferromagnetic Kondo Model
M. Daghofer, W. Koller, H. G. Evertz +1
We investigate the two- and three-dimensional ferromagnetic Kondo lattice model by unbiased Monte Carlo simulations. A phase diagram for the two-dimensional model is presented, in…

Single particle spectrum of the flux phase in the FM Kondo Model
M. Daghofer, W. Koller, W. von der Linden +1
We investigate the 2D ferromagnetic Kondo lattice model for manganites with classical corespins at Hund's rule coupling J_H=6, with antiferromagnetic superexchange 0.03 < J' < 0.05…

First- and Second Order Phase Transitions in the Holstein-Hubbard Model
W. Koller, D. Meyer, Y. Ono +1
We investigate metal-insulator transitions in the Holstein-Hubbard model as a function of the on-site electron-electron interaction U and the electron-phonon coupling g. We use sev…
