The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our results establish that transient charge dynamics can distinguish topologically trivial and nontrivial phases in real time by detecting the presence of topologically-protected edge states.

C2weakest assumption

The conventional view that charge oscillations are suppressed in gapped topological systems with preserved chiral symmetry is taken as the baseline to contradict, yet the abstract provides no explicit derivation or numerical protocol showing how the oscillations arise under that symmetry.

C3one line summary

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