Sažetak
A closed SU(2)_q quantum invariant spin chain is treated by the coordinate Bethe Ansatz method. The model is nonlocal and has sector dependent boundary conditions. Surprisingly, its ground state has vanishing or nonvanishing spin, depending on the value of the coupling constant. The central charge of the model is derived. For particular values of the
coupling constant we project a set of states which define partition functions of minimal unitary series. Their operator content is derived. In particular cases we exhibit corresponding hamiltonians which are also nonlocal and have sector dependent boundary conditions.
