Drinfeld twists and symmetric Bethe vectors of supersymmetric fermion models
Shao-you Zhao A, Wen‐Li Yang, Yao-Zhong Zhang
We construct the Drinfeld twists (factorizing F -matrices) of the gl ( m | n )-invariant fermion model. Completely symmetric representation of the pseudo-particle creation operators of the model are obtained in the basis provided by the F -matrix (the F -basis). We resolve the hierarchy of the nested Bethe vectors in the F -basis for the gl ( m | n ) supersymmetric model.
