Abstract
By constructing a complete set of coherent states that forbids double occupancy, we introduce a quantum Monte Carlo algorithm for simulation of fermion models with constraint, including the infinite-U Hubbard model and the t-J model. Application to the infinite-U Hubbard model on 4×4 and 6×6 lattices provides new physical results on the thermodynamics of the model, especially the temperature and doping dependence of the Nagaoka state.Keywords
