Abstract:

Using notation inherited from the six-vertex model, we construct diagrams that represent the action of the factorizing $F$-matrices associated to the finite length XXZ spin-1/2 chain. We prove that these F-matrices factorize the tensor $R^σ_{1...n}$ corresponding with elements of the permutation group. We consider in particular the diagram for the tensor $R^{σ_c}_{1...n}$, which cyclically permutes the spin chain. This leads us to a diagrammatic construction of the local spin operators $S^±_i$ and $S^z_i$ in terms of the monodromy matrix operators.
