The Bethe Ansatz

Rational \(R\)-matrix debab.Slavnov2018-3

This uses a rescaled version of Slavnov2018-2-2.3, divided by \(u-v\):

  • Slavnov2018-3-3.2

\[ R(u,v) = \boldsymbol{1} + \frac{c}{u-v} \boldsymbol{P} = \left( \begin{array}{cccc} f(u,v) & 0 & 0 & 0 \\ 0 & 1 & g(u,v) & 0 \\ 0 & g(u,v) & 1 & 0 \\ 0 & 0 & 0 & f(u,v) \end{array} \right) \]

  • Slavnov2018-3-3.2

\[ f(u,v) = \frac{u-v+c}{u-v}, \hspace{10mm} g(u,v) = \frac{c}{u-v} \]
