## Slavnov and Gaudin – Korepin Formulas for Models without U ( 1 ) Symmetry : the Twisted XXX Chain

- Samuel BELLIARD, Rodrigo A. PIMENTA
- 2015

We show that the algebra of commuting Hamiltonians of the homogeneous XXX Heisenberg model has simple spectrum on the subspace of singular vectors of the tensor product of two-dimensional gl 2-modules. As a byproduct we show that there exist exactly n l − n l−1 two-dimensional vector subspaces V ⊂ C[u] with a basis f, g ∈ V such that deg f = l, deg g = n… CONTINUE READING
