The sl_2 loop algebra symmetry of the six-vertex model at roots of unity

Tetsuo Deguchi, Klaus Fabricius, Barry M. McCoy

We demonstrate that the six vertex model (XXZ spin chain) with $Δ = (q + q^{- 1}) /2$ and $q^{2 N} = 1$ has an invariance under the loop algebra of $s l_{2}$ which produces a special set of de…
