具有束缚态II的可积模型中的楔局部场。对角S-矩阵

Wedge-local fields in integrable models with bound states II. Diagonal S-matrix

Daniela Cadamuro, Yoh Tanimoto

摘要:

通过推广我们以前的标量S-矩阵方法,我们构造了一类1+1维可积量子场论的楔形区域的候选观测量.例子包括Z(N)-伊辛模型、A_N-仿射Toda场论和一些带有CDD因子的S-矩阵。我们证明了这些与基本粒子相关的候选算子在稠密区域上弱交换。对于两种粒子的模型,我们可以取一个更大的弱交换性区域,并给出Reeh-Schlieder性质的一个论证。

英文摘要:

We construct candidates for observables in wedge-shaped regions for a class of 1+1-dimensional integrable quantum field theories with bound states whose S-matrix is diagonal, by extending our previous methods for scalar S-matrices. Examples include the Z(N)-Ising models, the A_N-affine Toda field theories and some S-matrices with CDD factors. We show that these candidate operators which are associated with elementary particles commute weakly on a dense domain. For the models with two species of particles, we can take a larger domain of weak commutativity and give an argument for the Reeh-Schlieder property.
