Zooming into the Landscape of Topological States and Collective Excitations

Nanoscale electrodynamics offers a unique perspective on states with bulk-edge correspondence or spatially-dependent excitations. This presentation will introduce our latest advancements in optically coupled microwave impedance microscopy, a technique that enhances our capability to explore electrodynamics at the nanometer scale. I will discuss our recent studies utilizing this technology to extract spectroscopic information on exciton excitations within transition metal dichalcogenide (TMD) systems. Additionally, I will share some of our recent findings on probing topological and correlated electronic states, specifically those induced by flat bands in twisted TMD bilayers.
