Collective spin dynamics of Z_{2} vortex crystals in triangular Kitaev-Heisenberg antiferromagnets
We show that the mesoscopic incommensurate Z_{2} vortex crystals proposed for layered triangular anisotropic magnets can be most saliently identified by two distinctive signatures in dynamical spin response experiments: the presence of pseudo-Goldstone phononlike modes at low frequencies ω, associat...
