报告内容：
After nearly thirty years of development, research on ultracold atoms has become one of the representative fields of atomic, molecular, and optical physics, providing powerful tools for studying fundamental scientific problems. In this seminar, I will discuss precision measurement techniques and the corresponding precision control techniques in ultracold atomic systems, with a focus on precision frequency techniques. I will further discuss the recent progress we made on building an ultra-stable laser with a 3-K single-crystal silicon optical cavity. I will also describe a few applications of precision techniques in ultracold atoms, such as the experimental realization of two-dimensional Dirac-type spin-orbit coupling and the Qi-Wu-Zhang model in ultracold fermions, and topological spin-orbit-coupled fermions beyond rotating wave approximation.
