Abstract: Abstract: We discuss electronic properties of a nanochain within the approach combining exact diagonalization with an ab initio calculations (EDABI method). The microscopic parameters of the second-quantized Hamiltonian are determined by minimizing the ground-state energy with respect to the single-particle wave functions defining them, and the system properties are traced in a systematic manner as a function of the interatomic distance. The evolution of the electron momentum distribution is analyzed in terms of the Tomonaga–Luttinger scaling, and the appearance of mixed metallic and insulating features (a partial localization) for the half-filled case is observed.
