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…

Ferromagnetism of magnetic impurities coupled indirectly via conduction electrons: Insights from various theoretical approaches
Irakli Titvinidze, Andrej Schwabe, Michael Potthoff
The magnetic ground-state properties of the periodic Anderson model with a regular depletion of the correlated sites are analyzed within different theoretical approaches. We consid…
