临界稠密聚合物选择定则的一个证明
A Proof of Selection Rules for Critical Dense Polymers
摘要:
在Pearce、Rasmussen和Zuber(2006)定义的晶格环模型中,对应于临界致密聚合物($β= 0$)的模型是Pearce和Rasmussen(2007)发现的唯一一个传递矩阵$D_N(u)$的反演关系。从这个结果中,他们确定了$D_N(u)$的可能特征值集,并对链路表示中具有$d$缺陷的扇区中其相关特征值的简并性给出了猜想。在本文中,我们开始证明这个猜想,使用之间的循环模型链接表示和$β= -(q+q^{-1})$的XXZ模型的$TL_N (β)$代数的同态。
英文摘要:
Among the lattice loop models defined by Pearce, Rasmussen and Zuber (2006), the model corresponding to critical dense polymers ($β= 0$) is the only one for which an inversion relation for the transfer matrix $D_N(u)$ was found by Pearce and Rasmussen (2007). From this result, they identified the set of possible eigenvalues for $D_N(u)$ and gave a conjecture for the degeneracies of its relevant eigenvalues in the link representation, in the sector with $d$ defects. In this paper, we set out to prove this conjecture, using the homomorphism of the $TL_N (β)$ algebra between the loop model link representation and that of the XXZ model for $β= -(q+q^{-1})$.
