In disordered variants of the Su-Schrieffer-Heeger model, the entanglement entropy difference ΔS^A between half-filled and near-half-filled ground states is zero in the topological phase and finite in the trivial phase, providing a robust diagnostic that can outperform the topological invariant Q.
Charge waves occur in SSH chains and their post-quench dynamics distinguish trivial from nontrivial topological phases through protected edge-state signatures.
