Topological property of a $t_{2g}^5$ system with a honeycomb lattice structure

Beom Hyun Kim, Kazuhiro Seki, Tomonori Shirakawa +1

A $t_{2g}^5$ system with a honeycomb lattice structure such as Na${}_2$IrO${}_3$ was firstly proposed as a topological insulator even though Na${}_2$IrO${}_3$ and its isostructural materia…
