On form factors in nested Bethe Ansatz systems
On form factors in nested Bethe Ansatz systems
We investigate form factors of local operators in the multi-component Quantum Nonlinear Schrödinger model, a prototype theory solvable by the so-called nested Bethe Ansatz.We determine the analytic properties of the infinite volume form factors using the coordinate Bethe Ansatz solution and we establish a connection with the finite volume matrix …
