The physically interesting intermediate regimen is also investigated, leading to the complete corresponding phase diagram, in which we classified some of these materials.

A rigorous study of electron correlations, magnetism and cluster structure within the topological Hubbard model is then surveyed. Current perspectives are discussed giving emphasis to finite temperature phenomena.

Our results confirm previous calculations performed within the 9-point approximation of the cluster variation method.

One finds a beautiful competition between this two phenomena giving as a result a reentrant superconducting behavior at low temperatures. In this system both ground states compete for the same portions of the Fer

Photoemission is applied to study surface properties of soot particles from the flame. It is shown that the surface of the particles is covered with PAH. By heating the PAH can be removed and the properties of the c
