摘要：
The excitation content of spectral functions of the 1D t-J model with nearest neighbor (n.n.) interactions is obtained from the Bethe-Ansatz solution at the supersymmetric point and compared with quantum Monte Carlo (QMC) simulations based on the hybrid-loop algorithm. We consider the one-particle spectrum as well as the dynamical spin and charge structure factors. The connection to the 1D supersymmetric t-J model with 1/r(2) interaction will be explained.
