报告摘要：

Topological quantum phases, originally discovered and investigated in condensed matter physics, have recently been widely explored in a range of different systems, which produced both fascinating physics findings and exciting opportunities for applications. Among the physical systems that have been considered to realize and probe these intriguing phases, ultracold atoms become promising platforms due to their high flexibility and controllability. Quantum simulation of topological phases with cold atomic gases is a rapidly evolving field, and recent theoretical and experimental developments reveal that some toy models originally proposed in condensed matter physics have been realized with this artificial quantum system. In this talk, I will introduce some of these developments, and will especially focus on addressing several topological quasi-particles described by relativistic quantum wave equations: Dirac, Weyl, Majorana and Maxwell quasi-particles. I will also present some topological phases in the Bose-Hubbard model.
