The novel properties of 5d transition metal oxides

In 5d transition metal oxides, novel properties arise from the interplay of electron correlations and spin–orbit interactions. In this talk, we focus on describing the topological Weyl-Semimetal in pyrochlore iridates, the Axion insulator in spinel osmates, the Slater insulator in perovskite osmates. We also discuss the anisotropic unscreened Coulomb interaction in ferroelectric metal LiOsO3, and the interesting properties of WTe2.
