内容简介:

    Layered ruthenates and rhodates continue to attract attention decades after their discovery in that new anomalous properties are still discovered and familiar ones present novel surprises. In this talk, I will introduce some recent advances obtained via the LDA+DMFT method in the understanding of their electronic, transport and magnetic properties. In particular, I will discuss the effects of the spin-orbit interaction and its interplay with crystal-field splitting in the presence of Coulomb interactions. I focus on Fermi surface, metal-insulator transition, optical conductivity as well as magnetic excitations in Sr2RuO4, Ca2RuO4 and Sr2RhO4.
