Transition metal oxides with partially filled 3d and 4d shells have dominated materials research in the past decades, leading to such spectacular phenomena as high Tc superconductivity and colossal magnetoresistance. In contrast, properties of materials like the oxides of rhenium, osmium and iridium, are only beginning to be explored. The presence of a large spin‐orbit coupling on the 5d elements, together with correlations, leads to the possibility of novel phases like topological Mott insulators and Weyl metals. The large variety of crystal structures (pyrochlore, hyper‐Kagome, etc.) in many cases leads to unusual anisotropic magnetic couplings and geometric frustration. Double perovskites with a 5d element are predicted, and in some cases known, to exhibit properties ranging from Mott insulators and spin‐liquids to insulating and half‐metallic ferrimagnets with very high Tc’s. Experimentally we know very little at this time about the effects of doping 5d Mott insulating phases. The aim of the workshop will be to bring researchers with diverse expertise in transition metal oxide experiments and theoretical modeling to focus on the latest developments in oxides with an interplay of strong correlations and spin‐orbit coupling.

Topics to be covered during the workshop:
• Magnetism: Spin and orbital ordering; Frustrated systems, Spin and orbital liquids,
• Multi‐orbital Mott insulators: role of spin‐orbit coupling; doping effects
• Topological properties: topological Mott insulators, Weyl metals, magnetoelectrics
