Theory of metal-insulator transition in the family of perovskite iridium oxides
Perovskite iridium oxides Sr${}_{n+1}$Ir${}_{n}$O${}_{3n+1}$ exhibit fascinating phenomena due to the combined effects of spin-orbit coupling (SOC) and electronic interactions. It was suggested that electronic correlation amplified via the strong SOC leads to a spin-orbit Mott insulator for $n=1$ and 2, while three-dimensional (3D) SrIrO${}_{3}$ remains metallic because of the large …
