J${}_{eff}$ description of the honeycomb Mott insulator $\alpha$-RuCl${}_3$

A. Koitzsch, C. Habenicht, E. Mueller +7

Novel ground states might be realized in honeycomb lattices with strong spin-orbit coupling. Here we study the electronic structure of $\alpha$-RuCl${}_3$, in which the Ru ions are in a d…
