关于AdS_3和AdS_2中twist的分解

On factorising twists in AdS_3 and AdS_2

Alessandro Torrielli

摘要:

本文研究了无质量AdS_3和AdS_2可积R-矩阵的分解扭曲,并探讨了Maillet等人为一般自旋链发展的形状因子分析程序。我们从gl(1)的泛R-矩阵导出了分解扭|1)Yangian double,并讨论了两点和三点单值矩阵的RTT关系。我们展示了如何扭曲可以用来计算一个简单的标量积。然后我们用自由费米子的语言实现我们的构造。最后,我们给出了如何从Yangian泛R-矩阵得到无质量的AdS_2量子R-矩阵,并计算了这种情况下的一个特殊的因子分解扭曲。

英文摘要:

In this paper we study factorising twists of the massless AdS_3 and AdS_2 integrable R-matrices, and explore the programme of analysis of form factors which Maillet et al developed for ordinary spin-chains. We derive the factorising twists from the universal R-matrix of the gl(1|1) Yangian double, and discuss the RTT relations for the two- and three-site monodromy matrix. We show how the twist can be used to compute a simple scalar product. We then implement our construction in the language of free fermions. Finally, we show how to obtain the massless AdS_2 quantum R-matrix from the Yangian universal R-matrix, and compute a peculiar factorising twist for this case as well.
