[理论室学术报告] Synthetic topological defects and synthetic spaces in ultracold atoms
Abstract: In this talk, I will discuss how to engineer laser-atom interactions for creating synthetic topological defects and synthetic spaces. Engineered couplings between internal states of ultracold atoms have allowed experimentalists to deliver a Yang monopole in laboratories. I will show that interactions lead to topological defects beyond the descriptions of single particle physics. Discrete defects may even be turned into continuous ones, a new type of “more is different” phenomena. If time allows, I will discuss a recent progress towards creating synthetic curved spaces.
