Ferromagnetic polarons in the one-dimensional ferromagnetic Kondo model with quantum mechanical S=3/2 core spins
D. R. Neuber, M. Daghofer, R. M. Noack +2
We present an extensive numerical study of the ferromagnetic Kondo lattice model with quantum mechanical S=3/2 core spins. We treat one orbital per site in one dimension using the…
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…
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…
Holstein polaron in two and three dimensions by quantum Monte Carlo
Martin Hohenadler, Hans Gerd Evertz, Wolfgang von der Linden
A recently developed quantum Monte Carlo approach to the Holstein model with one electron [PRB 69, 024301 (2004)] is extended to two and three dimensional lattices. A moderate sign…
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…
