DCA Calculations of the Kondo Lattice Model — •Lee Martin and Fakher Assaad — Universität Würzburg

We consider the two-dimensional Kondo Lattice model with exchange J and hopping t within the framework of the Dynamical Cluster Approximation. Results at different temperatures and different cluster sizes will first be compared with existing BSS results (1) at half-filling. We then move on to the doped lattice with the ultimate aim of mapping out the magnetic phase diagram as a function of doping and coupling J/t.
