Kitaev materials beyond iridates: order by quantum disorder and Weyl magnons in rare-earth double perovskites

, 2017
Motivated by the experiments on the rare-earth double perovskites, we propose a generalized Kitaev-Heisenberg model to describe the generic interaction between the spin-orbit-entangled Kramers' doublets of the rare-earth moments.
