Abstract

A finite-cell-scaling analysis of the spin-1 antiferromagnetic Heisenberg-Ising chain, shows that the ground-state properties are completely different than in the spin-½ case. Between the XY gapless phase and the doublet ground-state Néel phase, it appears, in an extended range of the anisotropy (0λ1.18) a characteristic Heisenberg-phase with a nonmagnetic singlet ground state, nonzero gap, and exponential decay of the correlation functions.
