In science:

This device works by effectively turning the MIT into a conventional metal-band insulator transition, thus masking the essence of the Mott phenomenon, where a charge gap appears quite independently of spin order.
Variational description of Mott insulators
In principle, were the pro jection complete, the GWF would indeed describe a Mott insulator devoid of symmetry breaking.
Variational description of Mott insulators
The main drawback of the GWF can be immediately recognized if one recalls Mott’s original description of a correlation-driven insulator.
Variational description of Mott insulators
In other words the long-range Jastrow factor not only restores gauge invariance, limq→0 Nq = 0, but also filters out either the metallic or the insulating component of the uncorrelated WF by an unbiased minimization of the energy.
Variational description of Mott insulators
Besides the small-q behavior of the charge structure factor Nq , another quantity which can discriminate between a metal and an insulator is a “rigidity” defined through Zc = hΨ|exp (cid:16) 2πi L Pj j nj (cid:17) |Ψi/hΨ|Ψi.
