What new things can we make from 2D Materials? The possibilities are incredibly varied, from novel quantum systems to functional nanoscale machines. In this talk, I'll discuss three things we've built: a tunable 2D exciton, a thermal guitar, and a new class of self-folding origami devices.

High-quality entangled-photon pairs are one of key resources for quantum computing and quantum information technologies. Since the observation of entangled photon generation via a biexciton from a CuCl bulk crystal, entangled photon generation mediated by the biexciton has been extensively studied. Recently, the biexciton of a CuCl thin film in a microcavity was observed, whose radiative decay was two times faster than that in the absence of the cavity (the Purcell effect of a biexciton).

This talk will overview the interplay between optics, plasmonics, and excitonics for systems that consist of arrays of gold, silver or aluminum nanoparticles in 1D, 2D and 3D. This will begin with a review of the use of classical electromagnetic theory to describe the optical properties of plasmonic particles of arbitrary shape, size and arrangement, and which leads to a variety of enhanced spectroscopies including surface enhanced Raman scattering.
