Abstract: Many-body cavity QED is a rapidly growing field known for intriguing correlated emergent phenomena, including "self-ordering" and "superradiance" [1]. Self-ordering – the spontaneous emergence of order out of disorder and chaos under some critical conditions – is a ubiquitous phenomenon not only in physics, but also in chemistry, biology, social sciences, and many other fields. The most well-known example in physics is the crystallization process, while the other commonly known general examples include the collective bird flocking and fish schooling. In this talk, I will first introduce the basic physics of self-ordering in open atom-cavity quantum systems, which is normally accompanied by the superradiance. I will then present in a pedagogical manner some of our works and predictions in many-body cavity QED. At the end, I will briefly discuss my future research plans.
