一般GL(2)自旋链的散射矩阵

Scattering matrix for a general gl(2) spin chain

S. Belliard, N. Crampe, E. Ragoucy

摘要:

本文研究了一般的L_0-正则gl(2)自旋链,即当链中{i,i+ L_0,i +2L_0,.}携带gl(2)的相同的任意表示(自旋)。对于L_0=2,我们得到了这种链的基本例子,其中我们恢复了交替自旋链。首先,我们回顾了关于它们的可积性和谱的不同已知结果。其次,我们给出了一个解释的粒子和猜测它们之间的散射矩阵。

英文摘要:

We study the general L_0-regular gl(2) spin chain, i.e. a chain where the sites {i,i+L_0,i+2L_0,...} carry the same arbitrary representation (spin) of gl(2). The basic example of such chain is obtained for L_0=2, where we recover the alternating spin chain. Firstly, we review different known results about their integrability and their spectrum. Secondly, we give an interpretation in terms of particles and conjecture the scattering matrix between them.
