Exact results on the Kondo-lattice magnetic polaron
S. Henning, P. Herrmann, W. Nolting
In this work we revise the theory of one electron in a ferromagnetically saturated local moment system interacting via a Kondo-like exchange interaction. The complete eigenstates f…
Ferromagnetism and non-local correlations in the Hubbard model
Sören Henning, Wolfgang Nolting
We study the possibility and stability of band-ferromagnetism in the single-band Hubbard model for the simple cubic (SC) lattice. A non-local self-energy is derived within a modifi…
The ground state magnetic phase diagram of the ferromagnetic Kondo-lattice model
S. Henning, W. Nolting
The magnetic ground state phase diagram of the ferromagnetic Kondo-lattice model is constructed by calculating internal energies of all possible bipartite magnetic configurations o…
Green function theory versus Quantum Monte Carlo calculations for thin magnetic films
S. Henning, F. Koermann, J. Kienert +2
In this work we compare numerically exact Quantum Monte Carlo (QMC) calculations and Green function theory (GFT) calculations of thin ferromagnetic films including second order ani…
