Dirac's equation is at the key of various quantum and topological effects in physics. In this talk I will show that how Dirac equation can be simulated in photonic and mechanical systems, as well as their physical effects. Photonic/phononic band gap with nontrivial topology leads to unusual surface states and reflection phases which are valuable for fundamental science and applications. Type-II Dirac points are shown to host anomalous refraction. Realization of robust bound states on dislocation as guaranteed by concurrent space and wavevector space topology is reported for photonic crystals.
中国科学技术大学本科、硕博连读博士。先后在以色列Weizmann研究所和加拿大多伦多大学从事博士后研究近5年。期间先后师从介观物理创始人Yoseph Imry教授（2016年沃尔夫物理奖得主）和光子晶体创始人Sajeev John教授（诺贝尔奖提名）。2015年被苏州大学引进回国，现任物理学院教授。在Physics Reports, Nature Communications, Physical Review Letters, Physical Review X, ACS Nano, npj Quantum Materials, Physical Review Applied, Phys. Rev. A/B/E, Optics Express等期刊上发表论文50多篇。曾发现半导体中载流子自旋弛豫的一系列普适性规律及其中多体散射机制的独特作用，并在Physics Reports上撰写半导体自旋耗散动力学的重要综述之一。作为早期的工作者之一，推动了介观非弹性热电输运领域的发展，在此方向开展了一系列的研究，并撰写了该领域第一篇综述论文。
