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 spectral function of quarter-filled ladder systems
M. Aichhorn, E. Ya. Sherman, H. G. Evertz
We study the single-particle properties of quarter-filled ladder systems such as sodium vanadate by means of a recently developed generalization of the variational cluster perturba…
Finite-temperature investigation of quarter filled ladder systems
C. Gabriel, E. Sherman, T. C. Lang +2
We investigate charge ordering in a quarter-filled ladder at finite temperature by determinantal Quantum Monte Carlo. The sign problem is moderate in a wide range of model paramete…
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…
Optical properties, electron-phonon coupling, and Raman scattering of vanadium ladder compounds
J. Spitaler, E. Ya. Sherman, H. G. Evertz +1
The electronic structure of two V-based ladder compounds, the quarter-filled NaVO in the symmetric phase and the iso-structural half-filled CaVO is investigated by…
Charge ordering in extended Hubbard models: Variational cluster approach
M. Aichhorn, H. G. Evertz, W. von der Linden +1
We present a generalization of the recently proposed variational cluster perturbation theory to extended Hubbard models at half filling with repulsive nearest neighbor interaction.…
