Pairwise entanglement and the Mott transition for correlated electrons in nanochains
Pairwise entanglement, calculated separately for charge and spin degrees of freedom, is proposed as a ground-state signature of the Mott transition in correlated nanoscopic systems. Utilizing the exact diagonalization— ab initio , for chains containing $N\leqslant 16$ hydrogenic-like atoms (at the h...
