Drinfeld Twists and Symmetric Bethe Vectors of Supersymmetric Fermion Models

arXiv:nlin/0502050 · doi:10.1088/1742-5468/2005/04/P04005

Abstract

We construct the Drinfeld twists (factorizing -matrices) of the -invariant fermion model. Completely symmetric representation of the pseudo-particle creation operators of the model are obtained in the basis provided by the -matrix (the -basis). We resolve the hierarchy of the nested Bethe vectors in the -basis for the supersymmetric model.
