Time-dependent density, n 0, of the central interacting site in a 5 × 5 × 5 simple cubic cluster subject to a step potential. The curves correspond to exact (thick orange), adiabatic (ALDA, thin black) and manybody (TMA, green) treatments for a weak (left) and strong (right) applied perturbation. Cl...
