Charge waves occur in SSH chains and their post-quench dynamics distinguish trivial from nontrivial topological phases through protected edge-state signatures.
The situation changes in the case of a chain in the topologically nontrivial phase, SSH1, where topological states appear at the edge atoms

Charge waves and dynamical signatures of topological phases in Su-Schrieffer-Heeger chains
Charge waves occur in SSH chains and their post-quench dynamics distinguish trivial from nontrivial topological phases through protected edge-state signatures.
