A note on $\mathfrak{gl}_2$-invariant Bethe vectors (1802.07576v1)
Published 21 Feb 2018 in math-ph, hep-th, and math.MP
Abstract: We consider $\mathfrak{gl}_2$-invariant quantum integrable models solvable by the algebraic Bethe ansatz. We show that the form of on-shell Bethe vectors is preserved under certain twist transformations of the monodromy matrix. We also derive the actions of the twisted monodromy matrix entries onto twisted off-shell Bethe vectors.
