...The close relationship between Fermi liquids and spin liquid states suggests an alternative picture of the Mott metal-insulator transition with respect to that put forward by Brinkman and Rice (Brinkman and Rice, 1970), who proposed that a metal-insulator (Mott) transition is characterized by a diverging effective mass m ∗ m → ∞ and an inverse compressibility κ → 0 at the Mott transition point, with a correspondingly vanishing quasi-particle renormalization weight Z ∼ mm∗ → 0....
