Separability and parity transitions in XYZ spin systems under nonuniform fields

We examine the existence of completely separable ground states (GS) in finite spin-s arrays with anisotropic XYZ couplings, immersed in a nonuniform magnetic field along one of the principal axes. The general conditions for their existence are determined. The analytic expressions for the separabilit...
