Abstract:

LDA+DMFT is a very useful method for correlated system. In this talk, I will discuss several application of this method: 1) An efficient method to compute magnetic exchange interactions in systems with strong correlations is introduced; 2) We calculate the many-body electronic structures of several Mott insulating oxides including undoped high Tc materials; 3) We discuss the competition between RKKY interaction and Kondo effect in PuAm alloy; 4) We study the long-range exchange interaction in high Tc materials.
