Abstract
A Su-Schrieffer-Heeger model is synthesized in momentum lattices of a Bose-Einstein condensate with tunable atomic interactions, and bulk dynamics is measured under various interactions. The breakdown of chiral dynamics in the synthetic atomic wire is observed with increasing strength of interaction, where the atoms are localized at the initial injection site under the strong interaction.
