Exotic criticality in the dimerized spin-1 $XXZ$ chain with single-ion anisotropy

We consider the dimerized spin-1 X X Z chain with single-ion anisotropy D . In absence of an explicit dimerization there are three phases: a large- D , an antiferromagnetically ordered and a Haldane phase. This phase structure persists up to a critical dimerization, above which the Haldane phase...
