演題：Optical functionalities using non-Hermitian nanophotonic systems
要旨：Recently, non-Hermitian physics has attracted considerable interest, particularly. It has not only expanded the frontiers of physics, but has also contributed to the emergence of novel functionalities through the application of its concepts to various physical systems. In particular, nanophotonic systems such as photonic crystals and metasurfaces have enabled a wide range of unconventional optical responses based on non-Hermitian physics that cannot be realized in conventional systems. We have proposed and experimentally demonstrated unique optical functionalities using exceptional points and non-Hermitian skin effect in photonic crystals and metasurfaces. In this talk, I will share these recent results.
