Dynamics and steady states of tight-binding chains in presence of isolated defects
A single isolated defect in a finite periodic tight-binding lattice induces nonlinear effects on wave-function spreading, including non-monotonic transport suppression, distant-site localization enhancement, and initial-position sensitivity at long times.
