Conservation of optical chirality in nanoscale light-matter interactions: A study of the Born-Kuhn model system
Kevin N. Moser, Marc R. Bourgeois, Elliot K. Beutler +1
Optical chirality density is a measure of the local handedness of electromagnetic fields. Like energy density, it may be absorbed or scattered through the interaction between light…
