在量子仿射代数下,基于六顶点模型的对称性,研究了它的高自旋类似物。使用最近开发的XXZ自旋链的方法,我们制定的状态空间,转移矩阵,真空,创建/湮灭运营商的粒子,和本地运营商,纯粹的语言表示论。我们发现,无论所涉及的表示的水平,粒子的自旋为1/2,并且n粒子空间具有RSOS型结构,而不是一个简单的张量积的一个粒子空间。这与Reshetikhin早些时候提出的情况一致。
We study the higher spin analogs of the six-vertex model on the basis of its symmetry under the quantum affine algebra . Using the method developed recently for the XXZ spin chain, we formulate the space of states, transfer matrix, vacuum, creation/ annihilation operators of particles, and local operators, purely in the language of representation theory. We find that, regardless of the level of the representation involved, the particles have spin 1/2, and that the n-particle space has an RSOS type structure rather than a simple tensor product of the one-particle space. This agrees with the picture proposed earlier by Reshetikhin.
