Tuning Topological Orders by a Conical Magnetic Field in the Kitaev Model
We show that a conical magnetic field $\mathbf{H}=(1,1,1)H$ can be used to tune the topological order and hence, anyon excitations of the ${Z}_{2}$ quantum spin liquid in the isotropic antiferromagnetic Kitaev model. A novel topological order, featured with Chern number $C=4$ and Abelian anyon excitations, is induced in a narrow …
