权位于亏格五曲线上的可积三态顶点模型

Integrable three-state vertex models with weights lying on genus five curves

M. J. Martins

摘要:

本文研究了$\mathrm{U}(1)$不变三态顶点模型的Yang-Baxter代数,该模型的玻尔兹曼权配置明显破坏了宇称-时间反转对称性.我们发现了两个家庭的定期拉克斯运营商的19个非零的权重,最终坐在代数平面曲线亏格5。我们认为,这些曲线承认度二态射到椭圆曲线,因此它们是双椭圆。相关的$\mathrm{R}$ -矩阵的光谱参数是非加性的,它已被检查,他们满足杨巴克斯特方程。展示了各自的可积量子自旋-1哈密顿量。

英文摘要:

We investigate the Yang-Baxter algebra for $\mathrm{U}(1)$ invariant three-state vertex models whose Boltzmann weights configurations break explicitly the parity-time reversal symmetry. We uncover two families of regular Lax operators with nineteen non-null weights which ultimately sit on algebraic plane curves with genus five. We argue that these curves admit degree two morphisms onto elliptic curves and thus they are bielliptic. The associated $\mathrm{R}$-matrices are non-additive in the spectral parameters and it has been checked that they satisfy the Yang-Baxter equation. The respective integrable quantum spin-1 Hamiltonians are exhibited.
