چکیده
We derive a formula that expresses the local spin and field operators of fundamental graded models in terms of the elements of the monodromy matrix. This formula is a quantum analogue of the classical inverse scattering transform. It applies to fundamental spin chains, such as the XYZ chain, and to a number of important exactly solvable models of strongly correlated electrons, such as the supersymmetric t-J model or the the EKS model. PACS: 03.65.Fd; 71.10.Pm; 71.27.+a

The Bethe ansatz equations of the 1-D SU(3) Hubbard model are systematically derived by diagonalizing the inhomogeneous transfer matrix of the XXX model. We first derive the scattering matrix of the SU(3) Hubbard model through the coordinate Bethe ansatz method. Then, with the help quantum inverse scattering method we solve the nested transfer matrix and give the eigenvalues, the eigenvectors a...

The Variational Method is applied within the context of Supersymmetric Quantum Mechanics to provide information about the energy and eigenfunction of the lowest levels of a Hamiltonian. The approach is illustrated by the case of the Morse potential applied to several diatomic molecules and the results are compared with stablished results.

We discuss observables in multiparticle production for three kinds of limits of decreasing kinematical scales: 1. the transition jet → hadron (limit ycut → 0 of the resolution parameter ycut); 2. single particle inclusive distributions normalized at threshold √ s → 0 and 3. particle densities in the limit of low momentum p, pT → 0. The observables show a smooth behaviour in these limits and fol...
