Speaker：Prof. 吳致盛(Jhih-Sheng Wu) 國立陽明交通大學光電工程學系/Department of Photonics, National Yang Ming Chiao Tung University Title：Light and 2D Dirac Fermions Abstract：Dirac fermions, originally proposed to explain relativistic electrons, turn out to appear in many condensed matter and optical systems, such as two dimensional materials and photonic crystals. Two-dimensional materials have shed light on finding new physics and novel phenomena in the past two decades. Fundamentally, such a trend is driven by the unique natures of 2D Dirac fermions such as 2D interactions, quantum confinements, Berry curvatures, and topology. Light is the key to manipulate these unique natures. Specifically, nano and ultrafast optics provide such interactions. I will introduce Dirac fermions from 2D materials with a honeycomb lattice. Such Dirac fermions live in a 2D world but interact with each other via 3D photons. I will talk my works related to the 2D-fermion-3D-photon system, including graphene plasmons, topological resonance and spaser with TMDC. Place：ON-LINE |
