Topological edge modes at topologically nontrivial quantum critical points (QCPs) give rise to anomalous dynamical scaling behavior, while bulk dynamics follow standard Kibble–Zurek (KZ) scaling. This anomalous boundary dynamics, demonstrated in quantum spin chains and free-fermion models, represents a modified scaling relation beyond the traditional KZ framework.
