Talk title: Understanding strong correlation effects in materials: from HTSCs to ruthenates.
Speaker: Eva Pavarini - Institute for Advanced Simulation, Forschungszentrum Jülich

Abstract: In the last decades, key theoretical advances and the increasing power of massively parallel supercomputers gave us access to the systematic study of strongly correlated materials, both at the single and two-particle level. In this talk I will present recent results for paradigmatic systems, high-temperature superconducting cuprates and layered ruthenates. For cuprates I will discuss spin-spin correlations and trends in the hopping integral range, t'/t; for ruthenates, the nature of the metal-insulator transition, Higgs bosons and the stability of xy-orbital ordering in the presence of sizable spin-orbit coupling [1-5].
