Abstract ： The electrical conductivity of the one-band Hubbard model on a two-dimensional square lattice at half-filling is studied through the grand canonical quantum Monte Calro method. Our results support that there exists an insulator-to-metal transition for the half-filled Hubbard model at high temperature.
