The work will take place within the BERNARDO project, funded by the PEPR LUMA program (https://www.pepr-luma.fr/). The project focuses on chiroptical interactions, which play an essential role in fields such as biomolecular recognition, optically active materials, and polarized light emission. At the nanoscale, however, these interactions remain poorly understood, especially regarding the relationship between near-field and far-field phenomena. It is often (and incorrectly) assumed that a strong chiroptical response in the far field necessarily implies strong chiral behavior in the near field. This simplification overlooks complex phenomena such as hidden chirality, where strong near-field effects are not observable in the far field.

To address these limitations, better characterization of chiral observables is necessary. Metrics such as optical chirality density, optical spin density, and the various elements of the Mueller matrix make it possible to quantify and control light-matter interactions at different spatial scales. The BERNARDO project aims to meet this challenge by designing nanostructures optimized to maximize these observables and by establishing fundamental connections between near-field and far-field chiral phenomena.

More specifically, the recruited researcher will develop experimental approaches to position quantum emitters within chiral hot spots in order to control their emission.
