Abstract
Probing the topological invariants of interacting systems stands as a grand and open challenge.
Here we describe a dynamical method to characterize 1D chiral models, based on the direct observation of time-evolving bulk excitations. We present analytical and state-of-the-art numerical
calculations on various flavors of interacting Su-Schrieffer-Heeger (SSH) chains, demonstrating how
measuring the mean chiral displacement allows to distinguish between topological insulator, trivial
insulator and symmetry-broken phases. Finally, we provide a readily-feasible experimental blueprint
for a model displaying these three phases and we describe how to detect those
