Phase diagram of the half-filled disordered Hubbard model at finite temperature

Institute of Physics, VAST

We study metal-insulator phase diagram in the half-filled disordered Hubbard model at finite temperatures. By means of dynamical mean field theory with an impurity solver of the equation of motion method, we calculate the averaged local density of states at the Fermi level and the site occupation as a function of the site energy at different temperatures. The paramagnetic phase diagram at finite temperature is constructed numerically and compared with the one at T = 0.
