contents The inelastic neutron scattering results and their analysis unequivocally point to a dominant Kitaev interaction in the honeycomb-lattice cobaltate BaCo$_2$(AsO$_4$)$_2$. Our anisotropic-exchange model closely describes $all$ available neutron scattering data in the material's field-polarized phase. The density-matrix renormalization group results for our model are in close accord with the unusual double-zigzag magnetic order and the low in-plane saturation field of BaCo$_2$(AsO$_4$)$_2$.
