摘要：
Quantum Monte-Carlo simulations of one-dimensional narrow band systems with attractive interactions (U < 0) have been reported. Using Hubbard model, local squared magnetic moments, probability of double occupancy, spin magnetic susceptibility and various spin pairing correlation functions as a function of Coulomb interactions for different band fillings have been studied.
