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…
Low Temperature Lanczos Method
Markus Aichhorn, Maria Daghofer, Hans Gerd Evertz +1
We present a modified finite temperature Lanczos method for the evaluation of dynamical and static quantities of strongly correlated electron systems that complements the finite te…
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…
Diamagnetic Properties of Doped Antiferromagnets
D. Veberic, P. Prelovsek, H. G. Evertz
Finite-temperature diamagnetic properties of doped antiferromagnets as modeled by the two-dimensional t-J model were investigated by numerical studies of small model systems. Two n…
