Georges et al , RMP 68, 13 (1996)

In the region between the dotted lines both

a metallic and an insulator solution exist

A gap between

Hubbard bands

opens at U c1

Mott transition

The quasiparticle peak

disappears at U c2

At zero temperature the Mott transition happens at U c2

when the quasiparticle peak disappears
