Abstract

Form factors are derived for a model describing the coherent Josephson tunneling between two coupled Bose–Einstein condensates. This is achieved by studying the exact solution of the model with in the framework of the algebraic Bethe ansatz. In this approach the form factors are expressed through determinant representations which are functions of the roots of the Bethe ansatz equations.
