Determinant representations for scalar products in the algebraic Bethe ansatz
N. A. Slavnov Steklov Mathematical Institute of Russian Academy of Sciences, Moscow, Russia
Abstract:
We study integrable models with $\mathfrak{gl}(2|1)$ symmetry that are solvable by the nested algebraic Bethe ansatz. We obtain a new determinant representation for scalar products of twisted and ordinary on-shell Bethe vectors. The obtained representation leads to a new formula for the scalar products in models with $\mathfrak{gl}(2)$ symmetry.
Keywords:
algebraic Bethe ansatz, scalar product, graded model.
