3-state Hamiltonians associated to solvable 33-vertex models
The goal of the paper consists in classifying models which are solvable by the coordinate Bethe ansatz. The authors study 3-state Hamiltonians with 33 non-vanishing entries, or 33-vertex models, where only one global charge with degenerate eigenvalues exists and each site possesses three internal degrees of freedom. In this case the local Hamiltonian is a \(9\times9\) matrix. Necessary and sufficient conditions for the Hamiltonian to be solvable are established.
