Abstract: In this seminar, I give a brief introduction to the quantum-classical analogy based on the same nature of wave behaviors. Two examples are presented in detail. One is the classical analogue of quantum interference. Owning to the new concepts inspired by quantum optics, novel interference behaviors are well designed in classical systems, which are called resonance induced interference. The other work is photonic simulation of the Dirac equation and one-dimensional (1D) topological phases. We show that the 1D metamaterials system closely mimics the topological state described by the two band Dirac model, such as band inversion, domain wall and end states. Microwave experiments are performed to confirm these ideas. This talk aims to provide a useful link between the study of photonics and electronic states, which may stimulate collaboration for future research.
