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…
Photoemission spectra of many-polaron systems
M. Hohenadler, D. Neuber, W. von der Linden +3
The cross over from low to high carrier densities in a many-polaron system is studied in the framework of the one-dimensional spinless Holstein model, using unbiased numerical meth…
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…
Temperature- and quantum phonon effects on Holstein-Hubbard bipolarons
Martin Hohenadler, Wolfgang von der Linden
The one-dimensional Holstein-Hubbard model with two electrons of opposite spin is studied using an extension of a recently developed quantum Monte Carlo method, and a very simple y…
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…
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…
