报告题目：Probing topological physics using photonic lattices
报告人：Daniel LeykamInstitute for Basic Science, South Korea
报告摘要：Light propagation in photonic lattices of coupled waveguides is governed by the paraxial wave equation, which closely resembles the two-dimensional Schrodinger equation. This enables the study of analogies with various quantum and condensed matter systems, providing novel ways to control the flow of light in photonics. I will review some of my recent work on observing various topological phenomena in photonics including Dirac cones, Weyl points, and non-Hermitian topological phases, as well as discuss prospects for nanophotonic device applications.
