U_q(\hat(sl_2))顶点模型的广义Q算子

A Generalized Q-operator for U_q(\hat(sl_2)) Vertex Models

Marco Rossi, Robert Weston

摘要:

在本文中,我们构造了一个Q-算子作为无限维辅助空间上$U_q(\hat{sl}_2)$的泛R-矩阵表示的迹。这个辅助空间是前面使用的q振荡器表示的四参数推广。我们推导出广义T-Q关系,其中3个参数的移动。在适当的参数限制后,我们给出了六顶点模型的Q算子的显式表达式,并指出了它与Baxter关于相应算子中心块的表达式的联系。

英文摘要:

In this paper, we construct a Q-operator as a trace of a representation of the universal R-matrix of $U_q(\hat{sl}_2)$ over an infinite-dimensional auxiliary space. This auxiliary space is a four-parameter generalization of the q-oscillator representations used previously. We derive generalized T-Q relations in which 3 of these parameters shift. After a suitable restriction of parameters, we give an explicit expression for the Q-operator of the 6-vertex model and show the connection with Baxter's expression for the central block of his corresponding operator.
