Mott Insulating Ground State and its Proximity to Spin-Orbit Insulators in Na${}_2$IrO${}_3$

Hosub Jin, Heungsik Kim, Hogyun Jeong +2

We present an anti-ferromagnetically ordered ground state of Na${}_2$IrO${}_3$ based on density-functional-theory calculations including both spin-orbit coupling and on-site Coulom…
