Chiral objects are not superimposable on their mirror image. This feature is ubiquituous in nature and can be found, e.g., in chiral molecules, in biological structures, and also in chiral electromagnetic fields. In order to better understand related phenomena, models and rigorous numerical simulations for the electromagnetic chirality density are required.

Metal nano helix and chirality density field


In this project, we analyze both theoretically and numerically chiral light fields on the nanoscale. Electromagnetic fields are described with the recently introduced optical chirality density and accessible observables of, e.g., extinction experiments are derived. Applications of these studies range from sensing of chiral analytes to chiral nanoplasmonics.
