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…
