Exact trimer ground states on a spin-1 chain
J. Solyom, J. Zittartz
We construct a new spin-1 model on a chain. Its ground state is determined exactly which is three-fold degenerate by breaking translational invariance. Thus we have trimerization.…

Phase Transitions Between Topologically Distinct Gapped Phases in Isotropic Spin Ladders
Eugene H. Kim, G. Fath, J. Solyom +1
We consider various two-leg ladder models exhibiting gapped phases. All of these phases have short-ranged valence bond ground states, and they all exhibit string order. However, we…

Opening of the Haldane Gap in Anisotropic Two- and Four-Leg Spin Ladders
Eugene H. Kim, J. Solyom
We study the opening of the Haldane gap in two-leg and four-leg anisotropic spin ladders using bosonization and renormalization group methods, and we determine the phase diagram as…
