Entanglement of disordered nanostructures as a function of the impurities’ concentration for several attractive (a) and repulsive (b) disorder strengths at a fixed U, and for several interaction strengths at a fixed V (c). (d, e) average occupation probabilities as a function of the impurities concentration: double occupancies (d) and single-occupation probabilities (e) at impurity (\(\bar{\text {w}}_2^V\), \(\bar{\text {w}}_\uparrow ^V\)) and non-impurity sites (\(\bar{\text {w}}_2^{V = 0}\), \(\bar{\text {w}}_\uparrow ^{V = 0}\)). In all cases \(L=100\) and \(n = 0.8\).
