Charge ordering in quarter-filled ladder systems coupled to the lattice
M. Aichhorn, M. Hohenadler, E. Ya. Sherman +3
We investigate charge ordering in the presence of electron-phonon coupling for quarter-filled ladder systems by using Exact Diagonalization. As an example we consider NaV2O5 using…
Polaronic Aspects of the two-dimensional Ferromagnetic Kondo Model
M. Daghofer, W. Koller, H. G. Evertz +1
The 2D ferromagnetic Kondo model with classical corespins is studied for a hole doping up to x = 0.125 via unbiased Monte Carlo (MC) simulations. A canonical algorithm for finite t…
Quantum Monte Carlo and variational approaches to the Holstein model
Martin Hohenadler, Hans Gerd Evertz, Wolfgang von der Linden
Based on the canonical Lang-Firsov transformation of the Hamiltonian we develop a very efficient quantum Monte Carlo algorithm for the Holstein model with one electron. Separation…
Magnetic Polarons in the 1D FM Kondo Model
Winfried Koller, Alexander Prüll, Hans Gerd Evertz +1
The ferromagnetic Kondo model with classical corespins is studied via unbiased Monte-Carlo simulations. We show that with realistic parameters for the manganites and at low tempera…
