We are in the midst of the so-called second quantum revolution, where quantum mechanics is increasingly being controlled to create novel engineered systems. From ultracold atoms and ions to solid-state realizations of quantum bits, these engineered systems are becoming increasingly powerful, but often at the cost of adding extra control knobs and thus complexity. In this talk I will show that, despite this complexity, universal structures nevertheless do emerge in the coherent quantum dynamics that define such systems. I will focus on two examples where the dynamics is closely related to quantum geometric and topological structure. I will first show how topological Chern numbers may be experimentally measured in simple few-level systems. I will then discuss a many-body problem where topological physics is crucial, namely the chiral anomaly of Weyl band structures in ultracold atoms. In both cases, I will show how dynamics plays a fundamental role in defining and measuring the universal structure, with important implications for future work.
