Multiple Spin-Orbit Excitons and the Electronic Structure of $\alpha$-RuCl${}_3$

P. Warzanowski, N. Borgwardt, K. Hopfer +7

The honeycomb compound $\alpha$-RuCl${}_3$ is widely discussed as a proximate Kitaev spin-liquid material. This scenario builds on spin-orbit entangled $j=1/2$ moments arising for a $t_…
