Exact solution of a supersymmetric Gaudin model

Julia Breiderhoff, Fabio Musso, Orlando Ragnisco

摘要:

研究了Gaudin模型中与超代数$osp(1,2)$有关的一种特殊情形.给出了自旋1/2表象下模型的精确解。一个完整的交换可观测量对角化和相应的特征向量和特征值显式计算。在本文中使用的方法是基于该模型的余代数对称性,已经知道从自旋1/2 Calogero-Gaudin系统。

英文摘要:

A special case of the Gaudin model related to the superalgebra $osp(1,2)$ is investigated. An exact solution for the model in the spin-1/2 representation is presented. A complete set of commuting observables is diagonalized and the corresponding eigenvectors and eigenvalues are explicitly calculated. The approach used in this paper is based on the co-algebra symmetry of the model, already known from the spin-1/2 Calogero-Gaudin system.
