Loop辫群与可积模型

Loop braid groups and integrable models

Pramod Padmanabhan, Abhishek Chowdhury

摘要:

环辫群刻画了三维空间中扩展对象(即环)的交换,推广了描述二维空间中点粒子交换的辫群的概念。他们对物理学的兴趣源于这样一个事实,即他们在三维空间中捕捉到了任何粒子的统计数据,而这些统计数据只存在于平面上的点粒子中。在这里,我们探索另一个方向,其中的代数关系的循环编织群可以发挥作用-量子可积模型。我们证明了{ \it对称环辫群}可以自然地产生杨-巴克斯特方程的解,通过RTT关系证明了某些模型的可积性。对于对称环辫群的某些表示,我们得到了$XXX$ -,$XXZ$ -和$XYZ$ -自旋链的可积形变.

英文摘要:

Loop braid groups characterize the exchange of extended objects, namely loops, in three dimensional space generalizing the notion of braid groups that describe the exchange of point particles in two dimensional space. Their interest in physics stems from the fact that they capture anyonic statistics in three dimensions which is otherwise known to only exist for point particles on the plane. Here we explore another direction where the algebraic relations of the loop braid groups can play a role -- quantum integrable models. We show that the {\it symmetric loop braid group} can naturally give rise to solutions of the Yang--Baxter equation, proving the integrability of certain models through the RTT relation. For certain representations of the symmetric loop braid group we obtain integrable deformations of the $XXX$-, $XXZ$- and $XYZ$-spin chains.
