Basically he points out that an MO wavefunction is like a metal and the VBS wavefunction describes a (Mott) insulator. So there is a phase transition (the Mott transition) separating them in the infinite xtal. This is in marked contrast to, say, H2, where both a approximations to the same (exact) wavefunction.Ben Powellhttps://www.blogger.com/profile/04312113344388752854noreply@blogger.com
