Introduction to solvable lattice models in statistical and mathematical physics

Tetsuo Deguchi

Some features of integrable lattice models are reviewed for the case of the six-vertex model. By the Bethe ansatz method we derive the free energy of the six-vertex model. Then, fr…

XXZ Bethe states as highest weight vectors of the $s l_{2}$ loop algebra at roots of unity

Tetsuo Deguchi

We prove some part of the conjecture that regular Bethe ansatz eigenvectors of the XXZ spin chain at roots of unity are highest weight vectors of the $s l_{2}$ loop algebra. Here $q$ …

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…
