M. Gulacsi et Ks. Bedell, THEORY OF METAL-INSULATOR-TRANSITION IN STRONGLY CORRELATED ELECTRON-SYSTEMS, Integrated ferroelectrics, 6(1-4), 1995, pp. 265-279
A comprehensive theory of the correlation driven metal insulator trans
ition in 1D and 2D strongly correlated electron systems is given. In b
oth the 1D and 2D Hubbard model the metal insulator transition encount
ered close to half filling is of Pokrovsky-Talapov type. An important
consequence of this in the 2D Hubbard model is the break down of the F
ermi liquid theory. We also describe in detail the properties of the P
okrovsky-Talapov transition in 2D ferroelectrics.
