摘要:

我们扩展的基本性质的二维可积模型内的代数Bethe Answer方法2+1维和制定的充分条件的交换矩阵的不同的谱参数,类似于杨巴克斯特或四面体方程。我们的模型的基本成分是R矩阵,它描述了一对粒子在另一对粒子上的散射,夸克-反夸克(介子)在另一个夸克-反夸克态上的散射。我们表明,Kitaev模型属于这一类的模型和它的R-矩阵满足定义良好的方程的可积性。

英文摘要:

We extend basic properties of two dimensional integrable models within the Algebraic Bethe Ansatz approach to 2+1 dimensions and formulate the sufficient conditions for the commutativity of transfer matrices of different spectral parameters, in analogy with Yang-Baxter or tetrahedron equations. The basic ingredient of our models is the R-matrix, which describes the scattering of a pair of particles over another pair of particles, the quark-anti-quark (meson) scattering on another quark-anti-quark state. We show that the Kitaev model belongs to this class of models and its R-matrix fulfills well-defined equations for integrability.
