RSOS路径中的粒子

Particles in RSOS paths

P. Jacob, P. Mathieu

摘要:

本文引入了Forrester-Baxter RSOS模型的一种新的路表示,它表示了极小模型M(p ',p)的不可约模的状态.对于p> 2 p '-2的情况,通过将RSOS路径变换为允许水平边缘在某些高度处的新路径来获得该表示。这些新的路径简单得多,因为它们的权重只不过是峰值位置的总和。这种描述为用费米型带电粒子解释RSOS路径铺平了道路,从中可以建设性地获得费米特征。给出了p ′ = 2和p= kp ′ +/-1时的费米子特征的推导。最后,把RSOS路径的粒子与限制sine-Gordon模型的扭结和呼吸子联系起来。

英文摘要:

We introduce a new representation of the paths of the Forrester-Baxter RSOS models which represents the states of the irreducible modules of the minimal models M(p',p). This representation is obtained by transforming the RSOS paths, for the cases p> 2p'-2, to new paths for which horizontal edges are allowed at certain heights. These new paths are much simpler in that their weight is nothing but the sum of the position of the peaks. This description paves the way for the interpretation of the RSOS paths in terms of fermi-type charged particles out of which the fermionic characters could be obtained constructively. The derivation of the fermionic character for p'=2 and p=kp'+/- 1 is outlined. Finally, the particles of the RSOS paths are put in relation with the kinks and the breathers of the restricted sine-Gordon model.
