三态哈密顿量的坐标Bethe变换分类

Classification of three-state Hamiltonians solvable by Coordinate Bethe Ansatz

N. Crampe, L. Frappat, E. Ragoucy

摘要:

我们分类所有的哈密顿与秩1对称性,作用于一个周期性的三态自旋链,并可通过(概括)的坐标Bethe anomaly(CBA)。我们以这种方式获得四个多参数的扩展已知的19-顶点哈密尔顿算子(如Zamolodchikov-Fateev,Izergin-Korepin,Bariev哈密尔顿算子)。除了19点哈密尔顿算子外,还有17点哈密尔顿算子和14点哈密尔顿算子不能被看作19点哈密尔顿算子的子情形。在17-顶点哈密顿量的情形下,我们得到了Martins发现的亏格5特殊分支的推广,并增加了三个新的亏格。我们还得到两个14顶点的哈密顿算子。我们使用CBA求解了所有这些哈密顿量,并给出了它们的谱、本征函数和Bethe方程。一个特别注意的是,提供我们的多参数哈密尔顿给回已知的哈密尔顿规范。

英文摘要:

We classify all Hamiltonians with rank 1 symmetry, acting on a periodic three-state spin chain, and solvable through (generalisation of) the coordinate Bethe ansatz (CBA). We obtain in this way four multi-parametric extensions of the known 19-vertex Hamiltonians (such as Zamolodchikov-Fateev, Izergin-Korepin, Bariev Hamiltonians). Apart from the 19-vertex Hamiltonians, there exists 17-vertex and 14-vertex Hamiltonians that cannot be viewed as subcases of the 19-vertex ones. In the case of 17-vertex Hamiltonian, we get a generalization of the genus 5 special branch found by Martins, plus three new ones. We get also two 14-vertex Hamiltonians. We solve all these Hamiltonians using CBA, and provide their spectrum, eigenfunctions and Bethe equations. A special attention is made to provide the specifications of our multi-parametric Hamiltonians that give back known Hamiltonians.
