Spectrum Doubling and the Extended Brillouin Zone Scheme in the Excitations of the 3-state Potts Spin Chain

Record type: Article

We compute the low-lying excitations of the integrable three state Potts spin chain over both the ferromagnetic and the antiferromagnetic vacua for Q = 0 and Q = 1. All the single particle levels are computed and for Q = 0, the composition rules for all the excitations are obtained. For the antiferromagnetic case a spectrum doubling and an extended Brillouin zone phenomena are observed.
