Electronic structure and parity effects in correlated nanosystems
Adam Rycerz, Jozef Spalek
Abstract
We discuss the spectral, transport and magnetic properties of quantum nanowires composed of N≤ 13 atoms and containing either even or odd numbers of valence electrons. In our approach we combine Exact Diagonalization and Ab Initio calculations (EDABI method). The analysis is performed as a function of the interatomic distance. The momentum distribution differs drastically for those obtained for even N with those for odd N, whereas the Drude weight evolves smoothly. A role of boundary conditions is stressed.
