hamiltonian and then promote the MF parameters to classical variables studied via MC simulations, while fermions are exactly diagonalized in the background of those classical variables. We present the Hubbard U vs. temperature phase diagram on large three and two dimensional clusters. Our MC-MF method can capture the nonmonotonicity of TN with U, local moment physics above TN, and the two peak behavior of specic heat, as compared with Determinantal Quantum Monte Carlo
