The Yang-Baxter Equation for the Chiral Potts Model and Integrable Parafermions (opens in new tab)

A new type of Yang-Baxter equation (YBE) for $R$-matrices parameterized by three spectral parameters is constructed from the star-triangle and star-star relations for the chiral Potts model. As the $Z_N$ symmetric generalization to the Ising model, its Boltzmann weights are known to depend on two variables describing a curve with genus larger than one for $N>2$, except for the self-dual point corresponding to the Fateev-Zamolodchikov chain.
