Abstract: Two-particle correlation functions provide a bridge between experimenals and theory. For strongly correlated systems, response functions can be determined with the LDA+DMFT method. In this approach the response function are extracted from the local two-particle vertex and the local Green's functions. Here we use such method and a Hirsch-Fye QMC impurity solver to calculate the response functions of correlated transition-metal oxides. As representative case, we present results for KCuF3.
