1. Efeitos de desordem na transição metal-isolante de Mott / Efects of disorder on the Mott metal-insulator transition
We determine the phase diagram of the disordered Hubbard Model as a function of temperature and interaction strength by means of the Statistical Dynamical Mean Field Theory. The metallic and insulating spinodal lines are traced for weak and moderate disorder using Quantum Monte Carlo as the impurity solver. We find that disorder pushes the spinodal lines to
