Abstract:
The description of the scattering of light by objects is one of the oldest problems in optics, and it continues to fascinate us. Particularly, the interplay between shape and materials enables advanced control over light-matter interactions. Understanding and predicting that interplay is a worthwhile endeavor for deepening our fundamental understanding of nature and for developing tangible technology. At the same time, modern algebraic, computational, and data-driven methods, emerging alongside machine learning, open new pathways for analyzing, designing, and optimizing scattering systems. In this talk, I review recent developments in this field.
As a small focus, I will present a framework for describing the optical response of nanophotonic scatterers in terms of quasi-normal modes (resonant states). Building on this, I show how the resonant-state expansion provides a quantitative description of strong coupling, offering a new perspective on its underlying mechanisms.
