FINALIST: Bingtian YeHarnessing many-body dynamics for quantum metrology in atomic, molecular and optical systems

The study of many-body dynamics aims to bridge the gap between the emergent collective behavior of strongly interacting systems and their microscopic intricacies. In recent years, advances in our ability to precisely control atomic, molecular, and optical platforms, combined with the ability to scale such systems up, has led to a fertile landscape for probing many-body quantum dynamics. Understanding how to characterize, classify and leverage such dynamics remains a central question at the intersection between the fundamental and applied sciences. In this talk, I will highlight the power of "emergent hydrodynamics", which offers a prescription for predicting the late-time dynamics of many-particle quantum systems using only a few key properties, such as their symmetries. Crucially, I will show that these hydrodynamic principles offer a universal framework for preparing metrologically useful entangled states. Perhaps the most striking consequence of this is a broad generalization and a systematic classification of the types of many-body Hamiltonians that can realize scalable spin squeezing.
