Title: Form factors of local operators in supersymmetric quantum integrable models,
Abstract: We apply the nested algebraic Bethe ansatz to the models with gl(2|1) and
gl}(1|2) supersymmetry. We show that form factors of local operators in these
models can be expressed in terms of the universal form factors. Our derivation
is based on the use of the RTT-algebra only. It does not refer to any specific
representation of this algebra. We obtain thus determinant representations for
form factors of local operators in the cases where an explicit solution of the
quantum inverse scattering problem is not known.
