Cooperation of different exchange mechanisms in confined magnetic systems
Andrej Schwabe, Mirek Hänsel, Michael Potthoff
The diluted Kondo lattice model is investigated at strong antiferromagnetic local exchange couplings J, where almost local Kondo clouds drastically restrict the motion of conductio…

Strong-coupling limit of depleted Kondo- and Anderson-lattice models
Irakli Titvinidze, Andrej Schwabe, Michael Potthoff
Fourth-order strong-coupling degenerate perturbation theory is used to derive an effective low-energy Hamiltonian for the Kondo-lattice model with a depleted system of localized sp…
