Topological Quantum Phase Transition in 5$d$ Transition Metal Oxide Na${}_2$IrO${}_3$

Choong H. Kim, Heung Sik Kim, Hogyun Jeong +2

We predict a quantum phase transition from normal to topological insulators in the 5$d$ transition metal oxide Na${}_2$IrO${}_3$, where the transition can be driven by the change of th…
