Resumen:
We discuss a general treatment based on the mean field plus random-phase approximation (RPA) for the
evaluation of subsystem entropies and negativities in ground states of spin systems. The approach leads to a
tractable generalmethod that becomes straightforward in translationally invariant arrays. The method is examined
in arrays of arbitrary spin with XYZ couplings of general range in a uniform transverse field, where the RPA
around both the normal and parity-breaking mean-field state, together with parity-restoration effects, is discussed
in detail. In the case of a uniformly connected XYZ array of arbitrary size, the method is shown to provide simple
analytic expressions for the entanglement entropy of any global bipartition, as well as for the negativity between
any two subsystems, which become exact for large spin. The limit case of a spin s pair is also discussed.
