Popis: We briefly summarize the fundamental properties of correlated nanoscopic systems obtained within the EDABI method combining an exact diagonalization in the Fock space with an ab initio readjustment of the single‐particle wave functions in the resultant ground state. Explicitly, we address the following questions: evolution of various systems from a nanometal to a nanoinsulator of the Mott‐Hubbard type, the appearance of the Mott‐Hubbard gap in molecular and cluster (Hn) systems, as well as the stability of those clusters.
