Fabio Musso, Matteo Petrera, Orlando Ragnisco, Giovanni Satta

摘要:

考虑一个与q-变形超代数${\CU}_q(\mathfrak{osp}(1 | 2))$相关的Gaudin模型.我们提出了一个精确的解决方案,该系统对角化一组完整的可交换的可观测量,并提供相应的特征向量和特征值。本文所用的方法是基于模型的余代数超对称性。

英文摘要:

We consider a Gaudin model related to the q-deformed superalgebra ${\CU}_q(\mathfrak{osp}(1 | 2))$. We present an exact solution to that system diagonalizing a complete set of commuting observables, and providing the corresponding eigenvectors and eigenvalues. The approach used in this paper is based on the coalgebra supersymmetry of the model.
