Sažetak
We treat a one parameter family of quantum spin models, which are quantum-group invariant as well as periodic in a certain sense, using Bethe states. We analyse its ground-state properties and obtain the surprising result that its spin becomes non-zero depending on the value of the parameter. Finite-size corrections allow us to obtain the central charge which is also spin dependent. Relations to other models are mentioned.
