TEACHING EXPERIENCE
For undergraduate courses, I mainly give lectures in classical mechanism and electromagnetism. Besides, I contribute several lectures of my research topics, for instance the progress in astrophysics, the mysterious Universe. I have contributed to the course of free style physics for undergraduates in SDU and ANU Joint Science College. For graduate courses, I have taught Group Theory, Radiation processes in astrophysics, and Active Galactic Nuclei.
RESEARCH INTERESTS
I will give a list for my research topics, now and future. Currently, I am interested in the both theoretical physics and astrophysics. For the latter, I mainly study the Active Galactic Nuclei (AGN) and Gamma-ray bursts(GRB). Emitting regions and variation of blazars are the primary topic. The prompt emission mechanism of GRB is also studied. The evolution of AGN and its cosmology relation is also interesting. Polarization information provides us with more information about the emission, and they are used to constrain models. All these studies aim to understand the radiation mechanism for high-energy astrophysics.
For the theoretical physics, I major in solitons, and study its dynamics. Solitons, especially the non-Abelian domain, play an important role in many branches of physics. The perturbation theory is the most successful part of theoretical physics.
The remained unresolved questions are most of the non-linear domain. To understand these non-linear phenomena, solitons are the bridge between the integrable and non-integrable systems. The dynamics of solitons indicate both the features of linear and non-linear aspects. Currently, we aim to understand the formation of fractal structure in the kink-Antikink collisions. The study of the non-Abelian vortices will provide deep insights in many branches, including the quark-confinement, the condensed matter physics. Especially, the moduli space of non-Abelian vortices manifests the GNO duality, which corresponds to the Langlands program in mathematics. The final aim of this program is to unify various branches of mathematics. Thus, the non-Abelian vortices may provide a net work to connect algebra, group theory, geometry in a visualized manner.
