My name is Xizhi Wu and I am 23 years old. I graduated from the Physics Department of Sun Yat-sen University in 2023, and then joined the research group of ultracold atomic systems of researcher Kaijun Jiang. Before that, I had a six-month internship in this research group. Now I am a first-year master student, and I have completed the study of quantum mechanics, statistical mechanics, atomic physics and other courses in undergraduate and postgraduate studies. At present, I'm taking a course in quantum optics and cold atomic physics. As I am very interested in ultracold atomic physics and related research fields, I was recommended by researcher Jiang to enroll in this summer course.
