Abstract
The electrical conductivity of the one-band Hubbard model on a two-dim ensional square lattice at half-filling is studied through the grand c anonical quantum Monte Calro method. Our results support that there ex ists an insulator-to-metal transition for the half-filled Hubbard mode l at high temperature.
