Former results for a Tight-Binding (TB) model of CuO planes in La2CuO4 arereinterpreted here to underline their wider implications. It is noted thatphysical systems being appropriately described by the TB model can exhibit themain strongly correlated electron system (SCES) properties, when they aresolved in the HF approximation, by also allowing crystal symmetry breakingeffects and non-collinear spin orientations of the HF orbitals. It is arguedhow a simple 2D square lattice system of Coulomb interacting electrons canexhibit insulator gaps and pseudogap states, and quantum phase transitions asillustrated by the mentioned former works. A discussion is also presented hereindicating the possibility of attaining room temperature superconductivity, bymeans of a surface coating with water molecules of cleaved planes of graphite,being orthogonal to its c-axis. The possibility that 2D arrays of quantum dotscan give rise to the same effect is also proposed to consideration. Theanalysis also furnishes theoretical insight to solve the Mott-Slater debate, atleast for the La2CuO4 and TMO band structures. The idea is to apply a properlynon-collinear GW scheme to the electronic structure calculation of thesematerials. The fact is that the GW approach can be viewed as a HF procedure inwhich the screening polarization is also determined. This directly indicatesthe possibility of predicting the assumed dielectric constant in the previousworks. Thus, the results seem to identify that the main correlation propertiesin these materials are determined by screening. Finally, the conclusions alsoseem to be of help for the description of the experimental observations ofmetal-insulator transitions and Mott properties in atoms trapped in planarphotonic lattices.
