Pair entanglement in dimerized spin-<i>s</i> chains

We examine the pair entanglement in the ground state of finite dimerized spin-s chains interacting through anisotropic XY couplings immersed in a transverse magnetic field by means of a self-consistent pair mean-field approximation. The approach, which makes no a priori assumptions on the pair state...
