Aspects of the FM Kondo Model: From Unbiased MC Simulations to Back-of-an-Envelope Explanations
M. Daghofer, W. Koller, A. Pruell +2
Effective models are derived from the ferromagnetic Kondo lattice model with classical corespins, which greatly reduce the numerical effort. Results for these models are presented.…
Uniform hopping approach to the FM Kondo Model at finite temperature
Winfried Koller, Alexander Pruell, Hans Gerd Evertz +1
We study the ferromagnetic Kondo model with classical corespins via unbiased Monte-Carlo simulations and derive a simplified model for the treatment of the corespins at any tempera…
Effective spinless fermions in the strong coupling Kondo model
Winfried Koller, Alexander Pruell, Hans Gerd Evertz +1
Starting from the two-orbital Kondo-lattice model with classical t_2g spins, an effective spinless fermion model is derived for strong Hund coupling J_H with a projection technique…
