Vortrag im Rahmen des University of Vienna Physics Colloquiums
Two-dimensional (2D) materials have extraordinary potential to control light and light-matter interactions on an atomic scale. Recently, twisted 2D materials have drawn considerable attention due to their capability of inducing moiré superlattices and the discovery of electronic correlated phases. Various nanoscale optoelectronic probing schemes, utilizing infrared and terahertz radiation, are presented, revealing the materials topology, photoconversion, interaction effects and even single photon detection capabilities. Furthermore, by probing modulated 2D materials on the nanoscale, record-small nanoscale polaritonic cavities are revealed, as well as the formation of nanoscale hypercrystals, exhibiting negative refraction and topological interface states.
A light lunch buffet will be offered before the lecture at around 13:00.
