Mott phase transition
NettetTo focus on the Mott transition, we neglect ordered phases such as the charge and spin density waves, and consider the paramagnetic solution with 〈n iσ 〉 = 0.5 at each site. … NettetFIG. 1. (Color online) (U,W) phase diagram obtained within TMT-DMFT for the disordered Hubbard model at T = 0.008. The description of the different symbols/colors used is given in the text. the metallic and the insulating spinodal lines of the first-order Mott phase transition; these two lines delimit the metal-insulator coexistence region.
